GPU change from Nvidia to AMD

I set up Bazzite with Nvidia drivers as I am currently using my 4080 Super.

I’d like to switch from that to an AMD gpu.

Is there any chance I can switch without having to reinstall? I’d like to do some benchmarks first… Thanks!

You can just tease to non-nvodia image. But even that is not required

What exactly do I have to do?

But even that is not required

Meaning I could just build my new GPU in and don’t do anything and everything works?

Yes. The required AMD drivers are in the kernel, so you can just keep using your current nvidia enabled image. Or if you want a little bit smaller image, you can rebase to non-nvidia image that just removes the nvidia drivers.
