If all you want to do is 464XLAT you don’t need a nameserver that supports DNS64.  Just add a ipv4only.arpa zone with the appropriate AAAA records to your recursive servers.

The following provides the 464XLAT translation with the well known NAT64 prefix.

ipv4only.arpa. SOA . . 0 0 0 0 0
ipv4only.arpa. NS .
ipv4only.arpa. AAAA 64:ff9b::192.0.0.170
ipv4only.arpa. AAAA 64:ff9b::192.0.0.171
ipv4only.arpa. A 192.0.0.170
ipv4only.arpa. A 192.0.0.171
