The ability to hide the Help Center would be great!

At the moment when working with different Service Desks we have many different corporate clients and we keep our clients confidential. When you have a Service Desk and you click on the Help Center, you can see all our Service Desks with all our various clients.

This should be an option, like a permission.
If the functionality is already there to hide this, then please ignore this suggestion, but note that I have spend hours trying to look for this functionality will continue to do so, until I can resolve this.
