The question was open-ended, and I'm still not sure what was requested.

If you want to swap a MAC at run-time within OpenVMS, set whatever MAC 
you want.

What DECnet does with the MAC is a documented API.

This does not alter the default MAC within the controller non-volatile 
storage, but does alter what is visible on the LAN.
