Yah, those distros have all this stuff preinstalled and I don’t have nVidia, but if you do there’s a place in the Nobara welcome screen to enable the nVidia drivers. GloriousEggroll, who does the Nobara distro, is one of the primary contributors to Proton.
Just a practice I’ve had over the years with domains: separate your registrar and your DNS. If one goes down, or out of business, you can fix it if you still control the other and its accessible. If you have both of them in one place, it’s really hard to get that domain transferred.
