No. It's not relevant for ARM 64. It's only relevant for BIOS systems, which are exclusive i386/amd64. ARM64 uses UEFI exclusively for booting, and has a combined boot loader for both ZFS and UFS systems (gptzfsboot exists because of space limitations on x86 and the kinda funky way that ZFS reserves space for a boot loader).
