Modify Thin Client Login GUI to Remove/Hide Fields From Users

Hi!

I'm looking to integrate Dell Wyse 5070 thin clients with ThinOS at my business but I want to modify the login GUI window. I'd like to not see any of the 4 buttons at the bottom of the login Window, I'd like to hide the DefaultDomain field entirely and hide the Connection Broker Server Name field entirely as well. Is there a way to do this with the Wyse Management Suite?
