might be wort looking into /var/cache/akmods/nvidia-390xx/390.138-3-for-5.9.15-200.fc33.x86_64.failed.log
I think the 390 driver is too old for the 5.9 kernel.
As your GPU is in the list of legacy GPUs, it’s not supported by current driver releases.
You should find an older kernel that works with this driver.
also all guides I’ve seen suggest creating a blacklist file in /etc/modprobe.d with this content:
blacklist nouveau
options nouveau modeset=0
