The dnsmasq RA code was designed to work with the dnsmasq DHCPv6 server, so there's no direct support for this. I think the closest you can get is to configure a static-addresses-only dhcp range dhcp-range=2001:470:xxxx:10::,static,slaac Which will not allocate any DHCPv6 leases, leaving the field open for you other DHCPv6 servers, but will set the M and O bits. Adding a new keyword to cover this circumstance is pretty straightforward.
