Yea, I bricked a Gigabyte board and still haven't been able to fix it. I just replaced it with an Asrock board and that has settings for what to do with option-rom when secureboot is enabled (always execute, always deny, allow execute, defer execute, deny execute and query user) and I have no clue what half of them specifically do (like, does "allow execute" only execute if a matching key exists and doesn't execute if it doesn't? and what is the difference between "always deny" and "deny execute"? and defer to when??). But I just set it to always execute and my problem is solved.
