Issue Creating IR in Azure Data factory with Terraform-CodePudding

I am trying to create an Azure Integration Runtime with VNet config Enabled. But when I try to run it with Terraform it gives the below error:

Error: Unsupported argument

  on DataFactory.tf line 44, in resource "azurerm_data_factory_integration_runtime_azure" "managed_ir":
  44:   virtual_network_enabled = true

An argument named "virtual_network_enabled" is not expected here.

My Terraform snippet:

resource "azurerm_data_factory_integration_runtime_azure" "managed_ir" {
  name                = "${local.prefix_kebab}-Managed-IR"
  data_factory_name   = azurerm_data_factory.datafactory.name
  resource_group_name = azurerm_resource_group.RG.name
  location            = azurerm_resource_group.RG.location
  virtual_network_enabled = true
}

I am not sure why it gives the ablove error as it is according to the documentation provided on terraform official website (
