Can Nginx duplicate TCP/UDP traffic? - nginx

Question

Below is my nginx.conf file, I have two upstreams, http_upstream and tcp_upstream, I make duplicated HTTP traffic and send it to load-balancer2.example.com:80 by using post_action, now I am wondering if I could make duplicated TCP/UDP traffic by using something similar to post_action?
