Do you have Secure Boot active? If you have and can't turn it off, you can try signing the module with a X.509 certificate and re-run the command. I did it some time ago by following the top answer here, i don't know if there is a more straightforward way to do it
Closing because this does not look like a problem that is specific to this module.
