Yes, it seems you do.

My understanding is that the gateway comes from the router
advertisements, so it's a radvd thing. There is no DHCPv6 option for
default gateway.

I'm seriously considering adding RA functionality to dnsmasq: just
enough to allow DHCP to work. That should make this sort of thing easier.

You can get a list of all the DHCPv4 options that dnsmasq knows about with

dnsmasq -w dhcp

and the same for DHCPv6 options with

dnsmasq -w dhcp6

The numbers are not the same for DHCPv4 and DHCPv6

You are giving a (very long) MAC address there, to set the DUID, you
need to precede it with "id:", so this should be

dhcp-host=id:00:01:00:01:15:E9:74:8C:XX:XX:XX:XX:XX:XX,2a01:AAA:BBB:0::2,Valkyrie
