SecureBoot is a UEFI setting. There is no way for the OS to determine whether it was intentional or not.

OK, so it is UEFI setting. That does not mean that the OS has to bug the user about this permanently. What about providing button "OK, got it, now get dismissed"?

I don't know the answer to that question, but if I was a malware writer, disabling that warning would be the very first thing I would do.
