DUID across VLANs

Hi,

I'm solving issue with DHCPv6 and Windows 10 connected by two interfaces 
into two different VLANs. One for ordinary data, the other one for 
network management.

Now, we have stations registered by MACs.

host milo.example.com {
         hardware ethernet 00:13:3b:9c:9f:ab;
         fixed-address6 2002:817:2:1100::ffff;
}

I'm aware that this is not the "RFC way", but registration by DUID would 
result into the same issue.

The problem is, that OS uses the same DUID for all ethernet interfaces. 
It is nice from the end-user point of view, cable can be plugged into 
any interface. But I need two separated IPv6 addresses for admin access 
and some netadmin tests.

Is it possible somehow to achieve that?

Thank you, Milo
