You can check if the system provides EFI variables using fwupdmgr. It
will look something like:

$ sudo fwupdmgr get-devices 2>&1 | grep -i -E 'UEFI|BIOS'
  │   Summary:            UEFI ESRT device
  └─UEFI dbx:
        Summary:          UEFI revocation database
        Vendor:           UEFI:Linux Foundation
        GUIDs:            c6682ade-b5ec-57c4-b687-676351208742 ←

                          f8ba2887-9411-5c36-9cee-88995bb39731 ←

There may be other ways to determine if EFI is available.
