 You can enable host-based encryption on existing clusters by adding a new node pool to your cluster. Configure a new node pool to use host-based encryption by using the `--enable-encryption-at-host` parameter.
 
 ```azurecli
-az aks nodepool add --name hostencrypt --cluster-name myAKSCluster --resource-group myResourceGroup -s Standard_DS2_v2 -l westus2 --enable-encryption-at-host
+az aks nodepool add --name hostencrypt --cluster-name myAKSCluster --resource-group myResourceGroup -s Standard_DS2_v2 --enable-encryption-at-host
 ```
 
 If you want to create new node pools without the host-based encryption feature, you can do so by omitting the `--enable-encryption-at-host` parameter.
