 Resources that support purge protection have them enabled by default. You can override the default configurations with
 the following variables:

 **Backup**
 
 To enable deployment of the backup module, you need to enable the following flag:

 **Private Deployment**
 
 To ensure access to GraphDB exclusively through a private network, you must set the following variables to `true`:
+
 ```hcl
 # Enable creation of a private service endpoint
 lb_enable_private_access = true
 # Enable private access to the Network Load Balancer and disable public access
