Default ECU power question?

Looking for suggestions, we are chassis wiring and do not have the engine wiring harness yet. (E38 ecu) we're installing a battery disconnect next to the battery controlled from a toggle switch at the instrument panel. I'm questioning whether we need to have constant power to the ECU if I will be using the battery disconnect frequently. IE bypassing the battery disconnect to power the ECU

Thanks!!
