It may well be, the code seems to set the lifetime to zero when
picking up a contructed deprecated address, but not an explicitly
configured one. Just to be sure, there are no other, non-deprecated
prefixes in the RA. That would affect things.

Yes, the DNS server address is taken from the DHCPv6 DNS server
option. So setting that to be empty will do the trick.


dhcp-option=option6:dns-server

If you want to remove the dns-server only from RA's and not DHCP
replies; use tags.



Cheers,

Simon.
