They have an Nvidia version; although it should be mentioned that Nvidia doesn’t always play nice with Wayland. If you use X11 with Nvidia instead, it’s a much better experience and you still get most of the benefits of using Bazzite.
Personally, I switched to AMD due to the better Linux support. Wayland on AMD is fantastic.
I’m now using Fedora CoreOS which can be deployed from config files. It’s really neat to be able to define everything the way you need it and just start up the VM with no further config necessary. I’m using podman to manage my services.
