Azure postgres flexible server dynamic HA setup

I would like to create a module that deploys a postgres flexible server where a var can be set to make the setup HA or not. But i cannot get this to work. I created the following code:

resource "azurerm_postgresql_flexible_server" "default" {
  name                         = var.databaseserver_name
  resource_group_name          = var.resource_group_name
  location                     = var.location
  version                      = var.postgres_version
  delegated_subnet_id          = azurerm_subnet.default.id
  private_dns_zone_id          = var.private_dns_zone_id
  administrator_login          = var.administrator_login
  administrator_password       = var.administrator_password
  zone                         = var.availibility_zone
  sku_name                     = var.sku_name
  backup_retention_days        = var.backup_retention
  geo_redundant_backup_enabled = var.geo_redundant_backup
  storage_mb                   = var.storage_mb

 dynamic "high_availability" {
  
  for_each = var.high_availability == "enabled" ? [] : [1]
  
  content {
     mode = "ZoneRedundant"
   }
  }
}

but this will create a HA setup even if var.high_availability is not set to enabled.
Is there a way to make this work ?

Try this var.high_availability == true ? :[1]
Make the variable high_availability a Boolean

Use Dynamic block for this
