[Simh] VAX/VMS 6.2 DECnet turned off, still resetting MAC address

Greetings,

I'm migrating a VMS 6.2 system from real hardware to simh VAX.
We're running on EC2 so DECnet's a no go.

We've disabled the DECnet startup on the system, but when I turn on tracing
I see:
DBG(42740138541)+> XQ ETH: writing  dst: 02:41:0C:98:92:09  src:
AA:00:04:00:20:10  proto: 0x0800  len: 98  crc: B5981F43

Is there a way to enable the debugging before booting up the VAX?
Barring that is there a way to prevent simh catching the "setup packet" and
changing the SRC MAC address?

-Bill
