I had a doubt about NAT64 for a long time! Is one docker container was ipv6 only and destination was ipv4 only, then docker has native NAT64 implementation?

NAT64 is only applicable when you are running an IPv6 only network but then you need a mechanism to connect to IPv4 only networks. The way you are describing it with Docker is not NAT64

Thanks for the standalone NAT64 demo! Is it possible to run Cilium agent as a CNI and also have it perform NAT64?

you can set this helm value `nat46x64Gateway.enabled=true` along with kube-proxy-replacement.
