I presume that the "disk utility" is Gparted. When I used it to mount the partition I could not see any little cogwheel. I am new to all this and maybe I did not understand you. I tried to change the boot order and got a "malformed" something for 0003. However, I should probably try to mount the partition first.
Not Gparted but Disks (should also be in your system utilities area or in all apps.
I have attempted to mount the partition by disabling the default option at the top and accepting all the given information below (since I had no idea what might be required). The partition remained unmounted as far as Disks was concerned.
I also tried to change the boot order to 0003, 2001, 0001, 2003 but was told "malformed BootOrder order 0003". The same thing happened when I changed 0003 to 0000.
Enter no space after the commas when you set the boot order in efibootmgr.

I have splited this EFI Issue now to a seperate Thread.

Thank you. I can now change the boot order. However, as NickS mentioned, neither partition with the Zorin EFI files is mounted. I have tried the Disks utility but it does not appear to have worked. I turned off the Default switch at the top and proceeded with the prefilled options since I did not know what they meant.

Is Secure Boot Disabled in your EFI Settings? Many Acer's will block GnuLinux distros booting up if it is enabled.
In your BIOS EFI settings, you may need to navigate to Security and from there, set "an EFI file as trusted" and select the ubuntu shim file.
Your output above shows that the Zorin EFI shim.efi file is installed (even duplicated...)
The duplicate Boot Order entries all point to the same file - so they are nothing to worry about. Probably a result of Boot Repair and attempts at setting the Boot.

You need to check the automount box after turning off the default switch.
I'll tell you how I installed Linux and Windows on separate drives, although I used a little trick to avoid having to swap the drives to boot into the BIOS every time.
I have different systems on different drives with different bootloaders.
sudo nano /etc/default/grub
GRUB_DISABLE_OS_PROBER=false - Searching for other systems on disks.
here you need to figure out how you prefer the selection menu or whether it will automatically move on in 3 seconds
GRUB_TIMEOUT_STYLE=menu - The selection display gives you the choice between systems right away.
GRUB_TIMEOUT_STYLE=hidden - It is hidden by default but these 3 seconds display it, if you do not select anything the system boot will continue by default.
GRUB_TIMEOUT=3 - gives a choice of 3 seconds, now I don't need to catch the GRUB window, it automatically appears at startup.
GRUB_DEFAULT=0 - Linux starts by default if I don't choose something else in those 3 seconds.
sudo update-grub
Unfortunately whether Secure Boot is enabled or disabled there is no option in the BIOS of my ACER Aspire 15 to accept an EFI file as trusted. I notice that on someone else's Aspire there was such an option.
Thank you for that suggestion. I am a novice with these things and it looks a bit scary for me at this stage. It may be worth a try if all else fails. There are people who say that for some ACER computers what I want to do may not be possible. It is beginning to look like that is the case here!
Maybe it helps to set a supervisor password to have more options in the BIOS

Good idea, This is what I did for my laptop (Acer) and this is what @Aravisian explained.
Set a supervisor password will give you this option, it is a known problem for many Acer

So just to check on the Ventoy front, did you use the latest version 1.12?
Also in your GParted images you have not labelled the root file system as '/' (without the single quote marks) or named it 'root', both column entries are blank.
Did you use Windows Disk Manager to create space for Zorin or were you trying the 'Install alongside existing OS'?
When I installed LMDE 7 using Ventoy for a client, during install a DOS like window appeared requesting to enrol EFI in the existing EFI, it then worked but in client's case it was to replace Windows.
Yes, I did use the latest version of Ventoy. I did use Windows Disk Manager to create a 100GB space for Zorin but I think I also clicked 'Install alongside existing OS' as I went through the Install process.
I am not sure I understand your comments about labelling or naming the root file system. If is has not been done am I able to do it now? If so, how?
I have set a supervisor password. The list at the top of the BIOS Security tab tells me that the HDD Password is 'Frozen" but I do not know what that means.
There are only two options under Secure Boot and no reference to trusted EFI file.
I did do this but it did not bring up the trusted EFI option (see the screen shot below).
Try to change the secure boot mode which is set to custom to standard and look if then the option appears to set an UEFI file as trusted.
I set the secure boot mode to factory settings but this did not change the option list.
