How to hide "server' response header

I’d like to hide the server response header. Dropping the header from virtual service definition doesn’t help.

  - headers:
        - x-envoy-upstream-service-time
        - server

x-envoy-upstream-service-time is removed but not server. What do I have to do to drop that header? or override the header?

This worked for me.

Thanks for sharing the information! It works for me.
