Prevent change workstation

I am trying to prevent users from changing workstations. There are workstations setup in Epicor and tied to an user. I need to prevent a specific user from changing to another workstation from what is listed under their user setup.

I did a trace and the logical “BO” is ICE.PROXY.LIB.SESSIONMODIMPL but Sessionmod is not listed in the methods in method directives search.

You cannot hide the button.

Has anybody have any experience with this or any ideas on how to accomplish this?
