Aha, great. And the answer was:
bash-5.2# sysctl machdep.bootmethod
machdep.bootmethod = UEFI

That’s what I suspected.

Yes, I saw that when reading docs. But that prompts the obvious followup question, especially given Matthias question to me about trying BIOS-booting my system. Is there any way to change from UEFI boot to BIOS boot without having to jeopardise my boot disk? And, preferably, also a way to change back.
I’m a little bit handicapped by only having one, single disk. I bought two, specifically to avoid being so dependent on one disk, but when doing that I always buy different brands, in the hope of not having them fail at the same time. Unfortunately the second M.2 disk simply did not fit into the box as it was too thick. I’ve ordered a replacement, but it will not arrive for a day or two.
