As promised, I merged all 3 parts of this Secure Boot series into one Field Notes document you can follow end-to-end.

This process is not trivial: some servers go through smoothly, others hit issues depending on firmware / platform / VM history. Thatโ€™s exactly why I wrote it down step-by-step, with the checks I actually used while testing.
