Yes, it is possible, just a major pain. Let me see if I can find a guide.
EDIT: You can ignore the bits about LVM (logical Volume Management) if you want:
This is more demonstrative, to show how much hair you'll lose.
To really throw grease into the fire, you would need to be substituting Zorin OS for Ubuntu, which would mean compiling packages as Zorin OS is not based on Ubuntu Server.
I read (or should I say glanced over?).
Something tells me it is easier to reinstall Windows in a non-RAID mode then install Linux in the usual way.
It sounds almost as complicated as installing macOS on PC...
I wouldn't do it.
I'd be in those UEFI settings flipping one switch lickity split and movin' on along the path to a normal installation. 
But I thought OP wants to keep the Windows installation along side with Linux.
Good point. Part of my own bias in how my thinking works...
When the installer asks me if I want to install alongside Windows, I'm clicking, "nope."
LOL
No re-install of Windows necessary:

Note the warning at the top to really make sure you couldn't get a needle up it with a sledgehammer.
I never met anyone that lost their Windows by that method or anything.
On a Linux page, a warning of that nature looks more like:
"And be sure to make back ups and be careful." That's it.
Glad I asked you about this [small] detail before you give OP an advice how to wipe his/her system clean before installing Zorin on it 
Just helping a fellow fix their computer. 
I love your euphemism 
try disabling fastboot windows 10 and formatting the partition that will be used for zorin to NTFS using MINITOOL/EASEUS Partision on windows 10. then try to reinstall zorin os as usual.
I've experienced it after installing windows 10 21H1 a few hours ago. I tried the method above and it worked.
I took an interest for this subject since I always thought RAID involves more than one drives. I checked around Dell forum and found this very interesting comment:
https://www.dell.com/community/Inspiron/Why-RAID-with-a-SIngle-Drive/m-p/7502665/highlight/true#M75285
Indeed there is such thing as a single disk RAID. But the avobe posting also mentioned that:
The only downsides to using RAID are that a) you can't run Linux, b) you can't use certain proprietary drivers and applications (like Samsung Magician if you install a retail Samsung SSD), and c) you may have to manually provide the Intel RST driver when performing a clean Windows install.
I started to wonder if some Linux distros incorporate elements which made them compatible with this default RAID setting.
A point, an SD card and an SSD card are not really the Same Thing.
eMMC is far more like an SD card than it is an SSD (drive).
In that regard, it makes sense to install Linux on an external USB drive to avoid such installation fiasco. From my experience, USB 3.0 drive runs faster than the internal microSD card reader and runs almost fast as internal eMMC (at least on my Rock64).
This also makes sense since Dell also sells Linux pre-installed laptops albeit in limited selections.
That is an interesting information.
When I got too old 
or too lazy to built my own computer, I should consider Dell products.
My experience is more or less the same as yours.
So far, the only machine which resisted my effort to install Linux was this newish Acer Aspire tablet with an eMMC storage.
I have figured out how to work around it, but my husband is currently using it as a score reader (he is a professional musician) and does not want me to experiment with it
