I am trying to create NIC card for VM through Azure ARM template. But my script also creates concats NIC to app gateway. But as of now I am only creating VM and NIC. Is there a condition to skip the Concatenation of App gateway and NIC. Below is the NIC creation template:

{
    "comments": "NIC_Creation",
    "tags": {
        "owner": "[parameters('owner')]"
    },
    "condition": "[equals(parameters('CreateVM'), 'yes')]",
    "dependsOn": [
        // "[resourceId('Microsoft.Network/publicIPAddresses', parameters('VM_PublicIP_Name'))]",
        // "[resourceId('Microsoft.Network/virtualNetworks', parameters('VNET_Name'))]",
        "[resourceId('Microsoft.Network/publicIPAddresses', parameters('VM_PublicIP_Name'))]",
        "[resourceId('Microsoft.Network/virtualNetworks', parameters('VNET_Name'))]",
        "[resourceId('Microsoft.Network/networkSecurityGroups', parameters('NSG_Name'))]",
        "[resourceId('Microsoft.Network/applicationGateways', parameters('AppGateWay_Name'))]"

    ],
    "type": "Microsoft.Network/networkInterfaces",
    "name": "[parameters('NIC_Name')]",
    "apiVersion": "2018-02-01",
    "location": "[parameters('myvmlocation')]",
    "scale": null,
    "properties": {

                    "privateIPAllocationMethod": "Dynamic",
                    "publicIPAddress": {
                        "id": "[resourceId('Microsoft.Network/publicIPAddresses', parameters('VM_PublicIP_Name'))]"
                    },
                    "subnet": {
                        "id": "[concat(resourceId('Microsoft.Network/virtualNetworks', parameters('VNET_Name')), '/subnets/',parameters('subnetname'))]"
                    },
                    "primary": true,
                    "privateIPAddressVersion": "IPv4",
                     "applicationGatewayBackendAddressPools": [

                        {
                            "condition": "[equals(parameters('CreateAppgateway'), 'yes')]",
                            "id": "[concat(resourceId('Microsoft.Network/applicationGateways', parameters('AppGateWay_Name')), '/backendAddressPools/sxBackendPool')]"
                        },
                        {
                            "condition": "[equals(parameters('CreateAppgateway'), 'yes')]",
                            "id": "[concat(resourceId('Microsoft.Network/applicationGateways', parameters('AppGateWay_Name')), '/backendAddressPools/nxBackendPool')]"
                        }
                    ]
                }
            }
        ],
        "dnsSettings": {
            "dnsServers": [],
            "appliedDnsServers": []
        },
        "macAddress": "00-0D-3A-1F-51-61",
        "enableAcceleratedNetworking": false,
        "enableIPForwarding": false,
        "networkSecurityGroup": {
            "id": "[resourceId('Microsoft.Network/networkSecurityGroups', parameters('NSG_Name'))]"
        },
        "primary": true
    }
},

I have added a condition inside applicationGatewayBackendAddressPools but it is not working. Can any one help me here please.

No, you cannot put conditions on individual properties. what you could do is use if() function together with variables and json() function to calculate desired result

"applicationGatewayBackendAddressPools": "[if(equals(parameters('CreateAppgateway'), 'yes'), variables('applicationGateways'), json('null'))]"

First of all, all the credits goes to https://stackoverflow.com/users/6067741/4c74356b41 (4c74356b41) who helped to solve this. Thanks for your help.

I used the IF function and implemented as shown below . It worked!!

"variables": {
    "AssociateNIC":  
    [{
        "id": "[concat(resourceId('Microsoft.Network/applicationGateways', parameters('AppGateWay_Name')), '/backendAddressPools/sxBackendPool')]"
    },
    {
        "id": "[concat(resourceId('Microsoft.Network/applicationGateways', parameters('AppGateWay_Name')), '/backendAddressPools/nxBackendPool')]"
    }]

},

"applicationGatewayBackendAddressPools": "[if(equals(parameters('CreateAppgateway'), 'yes'), variables('AssociateNIC'), json('null'))]"
