Fixed #3828

[Blayung]

• This fix issue: Archinstall installs nvidia-open-dkms instead of nvidia-open, even on default linux kernel. #3828 -->

PR Description:

I've added the ability to choose between dkms and non-dkms nvidia driver versions.

good change

[svartkanin]

This needs to be made backwards compatible as existing configurations that are loaded will not parse anymore

I like this change idea. Faster installs without dkms.

But then what happens if user picks custom kernel and nvidia driver non dkms

Also the headers would still be added regardless see:
