Yes, the installer (on x86) uses machdep.bootmethod to decide if the
system is new enough for UEFI, which works quite well, but not in your
case since you revert the required settings in the UEFI setup after
the installation.

It would be possible to add a manual override in the installer, but
currently there is no such thing.

But the part that I don't understand: why can't you get your machine to
boot the USB install image in UEFI mode? With stupid x86 firmware everything
is possible but I would guess it is more likely that some setting should
allow booting from USB in UEFI mode. Maybe the boot order settings
priorize CSM/legacy mode for USB over native (UEFI) boot and you can move
the UEFI USB boot up in the list?
