Hello,
I am a tech enthusiast and have been managing servers since I was 14.
So as I understand you need to install clover on your Linux mint.
Since Mint is already installed, this won't be possible. Clover needs to be setup first, then you can partition your drive and install mint on it.
Setting up NVIDIA drivers on your mac should be straightforward.
Lemme know if you are interested and I'll be more than happy to discuss these.
P.S. I am new on this site and am only looking to make my reputation for now so I am extremely high value for money. ;)
Best regards,
Umer
