Hi all,
i found a fix here:
https://launchpadlibrarian.net/712960879/nvidia-graphics-drivers-470_470.223.02-0ubuntu2.debdiff
Simply you need to edit the file
/var/lib/dkms/nvidia-legacy-390xx/390.157/source/nvidia-drm/nvidia-drm-drv.c
and apply this patch:

Replace all DRM_RENDER_ALLOW|DRM_UNLOCKED with DRM_RENDER_ALLOW (delete

Now it will compile successfully all nvidia modules.
