How to make NVIDIA the default card on Wayland?

[popus_czy_to_ty]

I need solution to make dedicated card running on everything without extra comand in Steam such as:

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command%

to run atleast games from steam on nvidia.
i want to run everything even browser on wayland.
wayland doesnt do anything else in nvidia-smi except runing uselessly /usr/lib/xorg/Xorg

It works when i change session to X11, but i dont want that obsolete thing anymore. (nvidia runs all programs )

Seen similar thread on arch forum, but cant find it right now.
Kubuntu 23.04, RTX 3050 M

1. where is problem, why wayland doesnt do anything?
2. how to force kde to run on nvidia card
3. how to run Q2PRO on nvidia, without typing extra command?

Edit:

Did you enable nvidia drm in grub, or something?
Are you using nvidia drivers preset by distro or compiled by yourself?
