Comment # 20 on bug 1182666 from Axel Braun

After cleaning /lib/modules/ from some old 5.5, 5.6 etc versions I triggered a
reinstall from the command line for

nvidia-gfxG05-kmp-default|460.39_k5.10.9_1-34.1|
nvidia-glG05|460.39-34.1
nvidia-computeG05|460.39-34.1
x11-video-nvidiaG05|460.39-34.1

Which brought back the modules:
X1E:/home/docb # find /lib/modules -name nvidia*.ko -exec ls -l {} \;
-rw-r--r-- 1 root root 3746408 16. Feb 15:12
/lib/modules/5.10.14-1-default/updates/nvidia-drm.ko

-rw-r--r-- 1 root root 49432392 25. Feb 16:20
/lib/modules/5.10.16-1-default/updates/nvidia.ko

and, no weak-updates...
This solved not the root cause, of the issue, but at least I can work again...
