Comcast Business - IPv6: DHCPv6-PD workarounds?

Hey all, so Comcast’s current IPv6 solution for business and residential is to run DHCPv6-PD to allocate prefixes...

I have a PAN attached to my business connection - which doesn’t do that...

Does anyone know: 1- if Comcast has done a true static routed allocation for v6 for anyone?

2- If I spin up a pfSense VM which can do PD Client stuff: can I create a route for the remainder of my prefix onto my PAN (and my other downstream layer 3 devices)? Or does DHCPv6-PD require all first hops to be attached to the original PD client?

PD is still new to me. Option 1 would of course be the least “patchy”, but that requires “the Comcast” to budge.
