Hide the Datastore List for User?

We need help with one case. While creating the VM Template we select a certain Datastore in Datastore List. But when User is attempting to order the VM with that Template, he can see the Datastore List. He is able to click that List, but it doesn’t respond 'cause we chose the certain Datastore before.
Is it possible to hide that unnecessary List for User? How should we do that?
