Does it not stay set at a default or have some amount of functionality? Like my Gigabyte Aorus has the full settings nonsense app in Windows, but if I set it to one thing, the change is persistent. I just always keep it on low and green. The function keys will let me alter the brightness between medium, bright, and alien abduction; which is super annoying because I can't get back to low, but there is something.

You may find some info searching too, some people occasionally make their own kernel modules or app for individual machines. I would take a look at Linux Hardware Probe (https://linux-hardware.org/) to see what shows up with your model, although the peripheral accessories are not usually the focus, they may be mentioned.

The main thing I was worried about with the proprietary settings like RGB was actually the thermal management settings that are also in that app. I have the 3080Ti, aka the 16GBV monster GPU. I can't say any details about how the thermal performance will work with gaming or whatnot, but I do some AI training loads that hold the GPU at absolute max load for hours and it has never gotten above 80C. It throttles as expected, and each laptop's thermal design will vary, but I can put the laptop with its vent inlet ports directly in front of a window AC and the GPU will hold max load at 70C for as long as I have ever pushed it (3-5hours straight). I'm playing with buggy code, much of it written by myself, and I never attempt to override the Nvidia settings, but with daily use since the beginning of July, I've had no complaints. This was the big thing weighing on me in the back of my mind. Just thought I might mention it if you change your mind and want to make the switch.
