I’m not sure on Debian, as Debian tends to sit on old releases of stuff for a long time. On Arch with KDE Plasma Wayland or GNOME Wayland, I just install nvidia-open-dkms and let it do its thing. Vulkan automatically uses the NVIDIA RTX 3070 in my Razer Blade 14 2021, no weird hacks or command line arguments required. Also, NVK is also quite usable, so I have set up rEFInd configs to boot with either NVIDIA driver loaded or nouveau. NVIDIA Settings is an antiquated tool and pretty useless if you’re using Wayland.
