Umm. So you asked a question, and then when you got an answer you said
"don't do that then".

The fact is, some hardware pushes secure boot pretty hard. That has
*nothing* to do with some "lockdown" mode.

Why do you conflate the two? That was the original question. You
replied with another question. People answered yours.

NOW ANSWER THE ORIGINAL QUESTION, DAMMIT.
