With nvidia_drm.fbdev=1 the screen freezes more than half of the time before the login screen regardless of kernel and other settings.

Wayland does not seem to work with kernel 6.9 and nvidia_drm.fbdev=0, a black screen appears when logging in, in X11 it works perfectly.

Edit:
I just found this: Talk:NVIDIA - ArchWiki

After reading X the solution for Wayland with kernel 6.9 is to add to /etc/mkinitcpio.conf:

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

Execute:

sudo mkinitcpio -P

Then add to GRUB_CMDLINE_LINUX

nvidia_drm.modeset=1 nvidia_drm.fbdev=1

But fbdev has other problems, it is also marked as an experimental feature.
