Usually you can't do this because not driver but NDIS created security
setting for device
due to Security Descriptor Definition Language (SDDL) in the driver calling
IoCreateDeviceSecure() inside.

Yes , but if default driver don't match the device , Device manager will ask
you about
driver for NIC

You'll see them in registry

As an example look at http://www.pcausa.com/Utilities/macaddr2.htm

Device Manager automatically bind miniport(s) ( driver(s) of NIC ) to layer
above : IM or protocol.
Miniport in NDIS have no knowledge about protocol above it , only NDIS
manage that.
