AIUI UEFI/GPT were designed to support multi-boot
Single EFI System Partition may contain loaders from different vendors, but not 2 Debian systems installed on different partitions. EFI files are signed for Secure Boot, so vendor paths can not be easily adjusted. I have no idea how much trouble may cause multiple ESP on the same drive. I tried ESP on different drives and it works (HP firmware on a decade-old laptop is quite buggy in respect to boot configuration). Actually GRUB menu to load system from alternative partition is more convenient than firmware boot menu in my case.
