OK. How exactly have you partitioned the target USB drive? What files
are on the EFI System Partition there? Did you tell the installer to
also install grub to the removable media path? That would be my first
guess for what's missing.

You don't need to tell grub-install to use x86_64-efi-signed as a
target - it should work things out automatically and install shim
etc. as needed. There is *not* a modinfo.sh for the signed grub
packaging as the signed binaries we build for grub are monolithic
(i.e. no loadable modules allowed).
