Question 1:

Is it set in the firmware to boot:
* UEFI only
* BIOS only
* Both, UEFI first?
* Both, BIOS first?

Q2:

Is your Ubuntu USB key standalone (should boot both types) or Ventoy?
I do not usually use standalone keys any more myself, because I find
Ventoy so much easier.

Still applies. UEFI or BIOS mode? Everything else afterwards depends on this.

This is why I ask.
