I tried to remove the network policy from aks cluster. but receiving below error with aks update command:

$ az aks update –resource-group rg-name –name cluster-name –network-policy none
ERROR: unrecognized arguments: –network-policy none

Examples from AI knowledge base:
az aks update –resource-group MyResourceGroup –name MyManagedCluster –load-balancer-managed-outbound-ip-count 2
Update a kubernetes cluster with standard SKU load balancer to use two AKS created IPs for the load balancer outbound connection usage.

az aks update –resource-group MyResourceGroup –name MyManagedCluster –api-server-authorized-ip-ranges 0.0.0.0/32
Restrict apiserver traffic in a kubernetes cluster to agentpool nodes.
