I generally use a Mac too, connected to Linux systems, but from the last time I disabled Secure Boot on a PC, the process was press F2 for Setup, go to the System tab in the BIOS, and uncheck Secure Boot, Save.
It's not particularly harder than a Mac: Restart in Recovery Mode, Launch a terminal, `csrutil disable`, Reboot.

Just like Mac "requires" it? I guess I just don't see how this is a "Windows sucks compared to Mac, let alone Linux" thing.
