Hello! Thank you for your response but unfortunately this is not what I am looking for :) gpt(8) works with partitions and, yes, it can modify some attributes. But I'm looking for a utility that can add netbsd loader into the UEFI boot menu.
Anyway, I have solved the problem by booting into FreeBSD live images and issuing: efibootmgr -a -c -l /mnt/EFI/boot/bootx64.efi -L NetBSD Now I have a "NetBSD" entry along with other OSes in the boot menu.
