I am wondering if the RTX 3070 Graphics card has been certified for Red Hat 7.9 and if so can you advise where I can find the drivers?
I don’t think there’s any “certification” regarding OS and consumer gpu. Please check these install instructions on how to install the driver on RHEL7
https://docs.nvidia.com/datacenter/tesla/pdf/NVIDIA_Driver_Installation_Quickstart.pdf
Those drivers don’t include the 32bit compat libs, though.
