insmod error "Operation not permitted" with secure boot enabled

[Cassiano-Gunji]

When trying to register the driver, insmod returns the error "Operation not permitted".

Searching the Internet, I suspect the culprit is that I have secure boot enabled. I'm not willing to disable it, since Windows in dual boot requires it now. Also, secure boot looks like a good idea.

Another solution seems to be to sign the driver like the answer in this post.

Since I'm far from capable and confident to start messing with this kind of thing, could you or anyone reading this write instructions or create a walkthrough to sign this driver?
