Thank you!
I am not familiar with Apple's implementation of Secure Boot so I've
read
https://support.apple.com/en-us/HT208330.
My current understanding is that the only way to start any other
operating system than macOS and Windows on this generation of Apple
hardware is, unfortunately, to disable Secure Boot entirely :(
(I initially understood that the "Medium" should work but further
reading lead me to believe it won't.)
