I think this has to do with the UP2 UEFI firmware, it gives me problem
on my UP2 board. I could never figure out what sequence of commands
would reliably set the boot order correctly but I also very often see
that setting a new entry with efibootmgr looks alright, until you
reboot and the boot order was changed (I suspect by the firmware
itself). It seems that I have had better luck with adding a new boot
entry *and* changing the boot order (efibootmgr -o).

Net net, your installation is most likely just fine but you're dealing
with a capricious EFI firmware.
Good to know I am not the only one who got this issue.

Maybe it would be worth mentioning it in the up2 doc section of acrn then.
I agree, I thought it was mainly my board up until now but I have had similar reports from others since then. I've added a note (PR still pending):
