Is NVRAM boot entries on your headless machine points to proper
partitions (efibootmgr -v)?
Do you sync EFI System Partitions after updating grub? In Debian grub
may update only one ESP.
I would try to put ESP on the USB drive, perhaps with both EFI/BOOT (for
removable drives) EFI/debian directories.
Is EFI/debian/grub.cfg points to a proper partition with boot?
If you use secure boot then you may just copy EFI/debian from the
machine where you installed Debian to the target machine (or to ESP on
the USB drive).
