I checked via command, but I'm not seeing EITHER DP0 or DP1. What am I supposed to do in this case? 
Is nomodeset enabled? (Are you booting in Safe Graphics?)
sudo nano /etc/default/grub
Arrow key down to this line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
Remove nomodeset (If present)
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
Tap ctrl+x to exit the editor, the y key to say yes to save and the enter key to save as current configuration.
Then you must run
sudo update-grub
Once done, reboot and test.
IF the nomodeset parameter is not present... please say so.
I checked, but the nomodeset is NOT present. So, what do I do now?
Can you please post the output of
sudo lshw -C video
(This may explain your missing Nvidia Settings, too)...
Ah... Nvidia 2070...
Can you run
sudo nano /etc/modules
And ctrl+shift+v paste at the bottom
nvidia
nvidia-drm
nvidia-modeset
Then ctrl+x, y, enter
Run
sudo update-initramfs -u
Reboot and test...
If that does not work, we may need to try lowering your kernel to maybe 5.10....
Okay, I'm going to reboot real fast & make those changes. brb

OK. I disabled Secure Boot & then rebooted, but the Nvidia X Server Settings is STILL not displaying right!
IS disabling Secure boot the only thing you did?
Yes. Was I supposed to have done something else...? If not, we can simply continue trying to figure out what's going on so. 
Yes, please see this post:
OK, but what am I supposed to do here? I'm dumbstruck atm. 
Nano is an editor for use in terminal.
Calling for SuperUser Privileges, sudo, you can run nano in Root:
sudo nano then specify the file to edit:
sudo nano /etc/modules
Arrow key to the bottom.
Copy the following here:
nvidia
nvidia-drm
nvidia-modeset
And at the bottom of the file in the terminal, tap ctrl+shift+v to paste, or right click and choose paste from the menu.
Once done, tap ctrl+x to exit, then the y key at the prompt to save, then the enter key to save the current configuration.
The terminal will revert to normal.
Now run
sudo update-initramfs -u
This should activate the necessary modules for Nvidia Graphics.
OK. I just did it. It may be possible I did it wrong or made a mistake earlier, but I'm honestly not sure. Do I need to reboot again for this to take effect?
You can run
sudo nano /etc/modules
and take a screenshot - post it here - then we can check if it looks ok.
It is correct.
Let's cross our fingers and all our toes...
Am I supposed to reboot or do I not have to?
Running sudo update-initramfs -u should be sufficient, but I would reboot anyway just to fully initialize the modules.
OK, then.
