There’s not really an upgrade path from Mint to a rolling release distro like Fedora or Arch. The simplest thing to do is rsync -axHAX
your /home
directory onto external storage and then install Fedora, Bazzite, Arch or EndeavourOS and copy data back as needed.
That’s not really the case with current Nvidia GPUs (yet anyway) - the Nvidia provided dkms driver is the best option outside very limited use cases
