If you're going to disable it for linux, you might as well disable it in the firmware. There's little point in having it enabled for just one OS if you're going to obfuscate it in the other.

I don't think that's the case, or possibly you've stumbled on a bug. You have UEFI 2.3.1 based hardware that implements Secure Boot and it's enabled?
