See [https://download.nvidia.com/XFree86/Linux-x86_64/570.153.02/README/installdriver.html#modulesigning Signing NVIDIA Kernel Module]. However, I didn't get an explicit message that signing was a problem; and I did see that the installation process signs the module with a generated key. I assume that the MOK process hooks into the trust system somehow. | On systems with Secure Boot enabled (mine), you most likely need to sign the module.
