VMware - preventing discovery of virtual desktops

VMware - preventing discovery of virtual desktops

Using OpManager 8 (8723)
 
We have added a number of ESX hosts and it picks up the virtual servers fine. However, we would like to add the hosts for the virtual desktops without the desktops being added to OpManager. We don't want to manage them or have them affect our license count.
 
Is this possible please?
 
Many thanks
John
