The rancher documentation says to use this command to create the ingress controller. But it creates a classic lb. How to fix? Plus I don’t want a public load balancer. I want a private NLB

helm upgrade --install \
  ingress-nginx ingress-nginx/ingress-nginx \
  --namespace ingress-nginx \
  --set controller.service.type=LoadBalancer \
  --version 3.12.0 \
  --create-namespace
