Sorry for the late response.
Thanks for the explanations.

Making things worse, many manufacturers treat their customers like
children, and have decided to refer to UEFI firmware as BIOS. So when
you go looking for firmware updates, you're likely to find them listed
as BIOS updates. It's just terrible. They should have just called it
what it is, firmware, from the outset and not caused end users to be
confused with either a new term, UEFI, let alone by interchanging two
different things, BIOS and UEFI, as if they are the same thing. But
that's where it is.
Indeed, my Gigabyte firmware is from 2018, and everywhere in the UI it says
"BIOS"! I looked (not very thoroughly), but couldn't find a toggle to
reenable UEFI. I guess I need to do a bit of searching on the weekend, it's probably
deep somewhere in the menu.
But depending on the age of the computer, make and model, there might
be hints somewhere that'll fairly conclusively confirm/deny if that
model has UEFI firmware or BIOS, and then also how to confirm whether
the faux-BIOS is enabled. For sure if the /sys/firmware/efi/efivars
directory exists, it's UEFI.
I'm guessing that's dynamic, present only if you boot with UEFI? It's not on
my system.
Thanks again, cheers,
