Right now, you can't.   The question is, why is this a problem?

We've been around on this a lot of times.   I don't see any reason to do it again.   But if you want to do it, you need to say why it's a problem that you have to do router discovery, why it's better to configure the DHCP server with router topology information, how you're going to get the right router link-local address to send, and why all of this complexity is somehow a better solution than router advertisements.

It's not good enough to just say "I'd really rather use DHCPv6 for this, can't we specify that?"
