Nvidia driver install Rocky 8 - how to?

Ok great. I went here and they say to do this

sudo dnf clean all
sudo dnf module disable nvidia-driver
sudo dnf -y install cuda```

The system fails then at installing cuda
```$ sudo dnf -y install cuda
Error: 
 Problem: package cuda-12-1-12.1.1-1.x86_64 requires cuda-runtime-12-1 >= 12.1.1, but none of the providers can be installed
  - package cuda-12.1.1-1.x86_64 requires cuda-12-1 >= 12.1.1, but none of the providers can be installed
  - package cuda-runtime-12-1-12.1.1-1.x86_64 requires cuda-drivers >= 530.30.02, but none of the providers can be installed
  - cannot install the best candidate for the job
  - package cuda-drivers-530.30.02-1.x86_64 is filtered out by modular filtering
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Looking at this site: ELRepo | kmod-nvidia it’s from 2015 and does not work or I cannot get it to work. And then there is the issue, that I won’t use the Tesla K80 for X but rather to calculate. Is there any other documentation out there?
