I was going to suggest package layering via `rpm-ostree install foo.rpm` but there are some compatibility issues with the nvidia rpms and rpm-ostree that don't quite work [1] [2]. Really you have two options. 1. unlock your ostree and install the rpms 2. build the kernel module for the kernel you are targeting and deliver via a system container like in https://github.com/giuseppe/hellomod The `unlock your ostree` approach basically converts the atomic host back into a system that is completely writable: - ostree admin unlock --hotfix - alias yum='/usr/share/yum-cli/yummain.py' - yum install -y epel-release kernel-{devel,headers}-$(uname -r) https://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-repo-rhel7-9.0.176-1.x86_64.rpm - yum install -y nvidia-kmod should do it. Sorry I don't have better answers on this right now.
