How to set max_conn for nginx ingress?

Question

I have Nginx Ingress Controller which is deployed via official Helm chart, in the doc I saw that I can set max_conn parameter, but I didn't get how to set it. I want to set it to 2, so that maximum of 2 clients could connect to my services. How do I set it? Should I set it in ingress controller values during helm install of Ingress Controller or in Ingress manifest?

From this document you can add these in the annotations

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: web-ingress
  namespace: default
  annotations:
    
    nginx.org/max-conns: 2

Try this and let me know if this works
