The problem happens earlier, before xorg gets started:
The nvidia module does not get loaded at boot.

I think something is "special" in your long grown system, some local
tweak long forgotten that now gets in the way of nvidia ...

/etc/modules-load.d/nvidia.conf should be responsible for loading the
nvidia-drm kernel module, while
/etc/modprobe.d/nvidia-blacklists-nouveau.conf prevents nouveau from
being loaded automatically.

Does manual 'modprobe -v nvidia-drm' work? If not, dmesg may contain
interesting error messages.

I saw this in your report that makes me suspicious: why is the radeon
module loaded?

PS: if nvidia-drm.ko is loaded, xorg should use nvidia automatically
