Disable FTP in Azure Policy

Hello all, is there an equivalent azure policy that disables the FTP of my applications in my subscription? If none, how can I disable the FTP of the applications under my subscription?

Available Effects
AuditIfNotExists, Disabled
Category
App Service

Json definition :
{
  "properties": {
    "displayName": "FTPS should be required in your Web App",
    "policyType": "BuiltIn",
    "mode": "Indexed",
    "description": "Enable FTPS enforcement for enhanced security",
    "metadata": {
      "version": "2.0.0",
      "category": "App Service"
    },
    "parameters": {
      "effect": {
        "type": "String",
        "metadata": {
          "displayName": "Effect",
          "description": "Enable or disable the execution of the policy"
        },
        "allowedValues": [
          "AuditIfNotExists",
          "Disabled"
        ],
        "defaultValue": "AuditIfNotExists"
      }
    },
    "policyRule": {
      "if": {
        "allOf": [
          {
            "field": "type",
            "equals": "Microsoft.Web/sites"
          },
          {
            "field": "kind",
            "like": "app*"
          }
        ]
      },
      "then": {

By the way if you want to disable both you cannot do that through policy but it's documented
To disable both FTP and FTPS entirely, select Disabled. When finished, click Save

Hi there is builtin policy to do that

Go to policy definitions blade :

Policy - Microsoft Azure

Search for ftp and you will see 3 policies :

FTPS only should be required in your Function App

FTPS should be required in your Web App

FTPS only should be required in your API App

Take the policy for the web app and assign it to your subscription or resource groups

Enforce the policy and add a remediation step with a managed identity (Deploy if not exists)

You can also manually enforce FTPs

The link below show how use FTP over TLS/SSL only (See Enforce FTPs section )
