grub is typically installed in /boot, and the efi directory is typically mounted at /boot/efi, which is where UEFI firmware looks for the EFI executable to load.
Following the same pattern, if grub is being installed in media/sdb1, the efi directory would be /media/sdb1/efi. I don't know if this is relevant in your particular environment, nor what your larger goal is, and have only an observation to offer.
