Yes. You basically need to use an "rtsold" that spawns dhclient -6.
We don't have a table of how to configure those, but I'd like it if
there were one somewhere.
Choose carefully however, because you want an rtsold that maintains
state; it has to remember if it started dhclient or not! There are
some rtsold's that will spawn a new dhclient on every RA it receives,
there are others that spawn a new dhclient every time the M or O bit
toggles from different routers...it is a more complex space than might
seem obvious at first encounter.
