Azure AKS internal load balancer

Hi,

I deployed an Azure AKS cluster via the following terraform statements into an existing vnet. It worked, the AKS cluster is created with an Azure load balancer and an public IP address assigned to it. I need a setup with an internal Azure load balancer only. How do I have to change the terraform code to only get an internal Azure load balancer? Thanks
