I want to have a way to execute low-level maintenance task via the EFI Shell and have a corresponding entry in the Boot Menu. It essentially should execute an EFI Shell script. From there I can call all the necessary actions.

While I can add the path to an EFI script to the boot menu with bcfg selecting it returns a failure dialog:
