Or, if you prefer not to rely on EFI boot variables (for example, Linux
GRUB EFI updates seem to reset them, deleting the FreeBSD entries), you
can also copy loader.efi into /mnt/EFI/BOOT/BOOTx64.efi (replace
BOOTx64.efi with BOOTarm.efi for ARM, and BOOTaa64.efi for AARCH64).

EFI\BOOT\BOOTx64.efi is the default place where UEFI system firmware
looks to run a bootloader from, given no EFI boot variables. I think
it's only supposed to be for removable media, but I've not come across
any that differentiate between fixed and removable.
