It used to be a pain. Multiple versions that didn’t all work. Today it’s pretty painless. A lot of installers will actually do it for you now.
In arch (at least the last time I did it), it was just a matter of picking the right package and installing it with pacman
EndeavorOS’s installer will do it for you
I use Fedora these days. It didn’t do it automatically the last time I loaded from scratch (not an upgrade), but the rpm fusion team/repository made it simple. I just followed the crystal clear instructions on their website.
I think mint does it automatically with the installer…
Honestly I really don’t even think about nvidia drivers anymore.
Its main purpose is to prevent malware from booting. In my experience its main purpose seems to be preventing me from booting things I want like ventoy flash drives, nvidia drivers, and Linux distros that don’t support it. Same goes for tpm module. Its main purpose seemed to be the switch keeping win 10 from upgrading. I turned them both off and haven’t felt the strong need to turn them back on yet.
That said, and my bad computing habits aside, you probably should turn them ON. I’m not sure they will do all that much realistically speaking, but if it isn’t getting in your way (and it shouldn’t), then ON isn’t a bad default state to be in.
