I've been using Clevo laptops for years. Large user base, lots of great Linux support. I just run Ubuntu, haven't had many issues (and no critical issues).
They usually get rebranded, and I've gotten them through IBuyPower, Origin, and... can't remember the other one. My most recent one was just straight up marketed as a Clevo, got it on Amazon.
You might have one or two odd issues (like having to install custom code to configure the RGB key backlights), but there are plenty of users to ask for assistance on various forums and repos.
I've been using nVidia cards on laptops with Ubuntu much exclusively for ~15 years . Only problem I've ever had was once when I accidentally uninstalled something using apt-get and it took the nvidia drivers with it (because I'm was stupid).
