Rancher Ingress - How to set server_tokens=off?

I try to hide ingress (nginx) version from header. For standalone nginx, I can set configuration as “server_tokens=off” in nginx.conf. But when using for ingress, I don’t know how to set it.

So, how can I set “server_tokens=off” in Rancher Ingress ? is it possible to do it using Rancher UI ?

I got the solution. Just go to cluster > system namespace > config map > nginx-configuration and add following key


then re-deploy nginx-ingress-controller
