Need help with Linux Clear OS

I’m attempting to help a friend who is the lead player in his school’s effort to help with scientific computing, including BOINC, and he is trying out Linux Clear OS. There is little documentation online for Clear when compared to Linux Mint or Linux Ubuntu. I did find a few though:

He is running two workstations each with a Threadripper 2970WX and a Nvidia RTX 4090 SUPRIM Liquid X. He is having difficulty getting Nvidia drivers to work on his 4090 Suprim Liquid X. Any help would be greatly appreciated.
