You can't return to loader.efi from the kernel, from what I can tell. loader.efi executes the ELF kernel through a trampoline: https://github.com/freebsd/freebsd/blob/433bd38e3a0349f9f89f9d54594172c75b002b74/stand/efi/loader/arch/amd64/elf64_freebsd.c#L197-L200
Defined here: https://github.com/freebsd/freebsd/blob/433bd38e3a0349f9f89f9d54594172c75b002b74/stand/efi/loader/arch/amd64/amd64_tramp.S#L40 The only way to get back to EFI that I see is through a system reset or some dark voodoo that switches back to efi_main directly (the mystic arts will likely be harder than just figuring ACPI out, though :P).
