This is from uefi(8) on fairly recent stable/11:
2. boot1.efi reads boot configuration from /boot.config or
/boot/config. Unlike other first-stage boot loaders,
boot1.efi passes the configuration to the next stage boot
loader and does not itself act on the contents of the file.
3. boot1.efi searches partitions of type freebsd-ufs and
freebsd-zfs for loader.efi. The search begins with partitions
on the device from which boot1.efi was loaded, and continues
with other available partitions. If both freebsd-ufs and
freebsd-zfs partitions exist on the same device the
freebsd-zfs partition is preferred. boot1.efi then loads and
Apparently, there are some options. Using /boot.config or /boot/config
on the ESP. Using /boot/loader.conf whereever /boot/loader.efi
resides. Relocating loader.efi to wanted the UFS partition. Note the
preference towards ZFS when both are present. I don't have any
experience using either option.
