Need to configure the Kong Ingress controller with Azure Internal LB

I have a private AKS cluster and I am trying to configure the ingress for this AKS cluster. I am planning to use the Internal LB for Azure by annotating the the Kong Proxy service with
annotations: “true”

Need guidance how can I add the annotation during the install of Kong Ingress controller using helm by passing a parameter. I did try using below command but it did not work as I can see a public Azure LB in the cluster resource group

helm install kong/kong
–namespace ingress-kong
–generate-name --set ingressController.installCRDs=false
–set service.annotations.“”=true

This has been resolved azure - Not able to annotate the Kong ingress controller with AKS private load balancer - Stack Overflow
