Can you try copying /boot/loader.efi into /mnt/efi/freebsd/loader.efi 
(after mounting the ESP on /mnt with e.g. `mount_msdosfs /dev/ada0p1 
/mnt`) and run the following command to set up the UEFI boot entry:

efibootmgr -c -a -L FreeBSD -l /mnt/efi/freebsd/loader.efi

Then, reboot and bring up the BIOS boot selection menu (often F8, or 
sometimes F11) and select the FreeBSD entry.
