Problem installing RTX 4000 on powerdge T640

I’m trying to install and use my Nvidia cuda RTX 4000 in Ubuntu 22.04.3

I’ve installed the drivers using sudo ubuntu-drivers autoinstall

When I use nvidia-smi the output tells me ‘no devices were found’

nvidia-bug-report.log.gz (249.7 KB)

Can anyone help me please ?

Did you even take a look at dmesg, journalctl -b0, or kern.log?
Maybe the answer is right there:
