Yes, that makes sense. All of the above drivers are UEFI drivers that
follow the UEFI driver model, AIUI. As long as the controller is not
connected from BDS, no BindingStart() function should be called in these.

E.g. EFI_DNS4_PROTOCOL.Configure() can only be called if an instance of
that protocol exists (... for the NIC in question), but the protocol
instance won't exist unless BDS (or some other agent such as the shell
or the boot menu app) called ConnectController().
