Wait this means all boards uses the same GUID ?
The GUID is generated at runtime based on the devicetree compatible string and the fw_image name. (https://docs.u-boot.org/en/latest/develop/uefi/uefi.html#dynamic-firmware-update-guids) So this means each board should get a unique GUID, based on the compatible, and in addition, based on which storage device it is booted from, as the fw_image name is different depending on the boot device.
