No. You just have to be connected to net while installing because
Archboot will pull the package from the repos and install it for you
automatically.

It is not present in the iso because very few systems have 32-bit EFI.
Thats also the reason why 32-bit EFI booting support was removed from
the iso, so reduce space.

The installer script (/arch/setup) supports grub2-efi-i386
installation. But the iso itself will not boot in EFI mode in 32-bit
EFI, and the package is not present in the iso (so you need to be
connected to net)

efibootmgr (and efivars module) may brick the firmware, but i don't
think bless or mactel-boot will corrupt it since they modify only at a
filesystem level.
