[ 13.973636] nvidia: module license 'NVIDIA' taints kernel.
It’s this line where the kernel notes why it is tainted. Somewhere
in
the nvidia kmod C code, there is a line that looks like this:
MODULE_LICENSE("NVIDIA");
The kernel will print out the aforementioned kernel message if it
isn’t one of the open licenses defined in the kernel. There’s more
about tainted kernels here:
https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html
There are a variety of reasons why the kernel would be tainted, but
in
this case it is because a proprietary kernel module was loaded. It
doesn’t have anything to do with signed kernel modules or secure
boot.
I thought the akmod version of the nvidia driver was the version that
was compiled every time the kernel version was changed, is that not
the case?
It's compiled as a module, but uses the Nvidia blob. It's not free
software.

If I remember your original email, you have successfully created and installed a key to sign the modules with (and maybe even signed the original module). If you have kept the key, you will not have to generate and install another one, but every time you install a new kernel, a new set of nvidia modules will need to be created and then signed. When I install a new kernel, the nvidia modules are created automatically, but after they are created, I have to manually sign them. I hope this is relevant to your original question.
