Disable direct file restore in Veeam vCloud Self-Service portal

The Veeam vCloud Self-Service portal (from here on, just portal) is a great solution for offereing self-service capabilities to vCloud Director tenants that want to manage by themselves backups and restores of their VMs and vApps. Service providers can already configure the service to allow tenants for different degrees of freedom, but there are some additional options that are not available in the configuration options.
I already blogged a few months ago about how to “Disable Items Restore options in Veeam Self-Service Backup Portal”, so that the ITEM tab can be completely removed from the interface. And looking at the number of visit this page has had so far, seems like several providers are alreday leveraging this “trick”.
Today however, we want to go a little bit further, and allow tenants to only download their files.
