An endpoint (Bigfix client) can only communicate to a single Bigfix server, based on the masthead (aka actionsite.afxm) file installed in the client folder.
An endpoint can be redirected to a different Bigfix server by switching out the masthead for a different one, and then restarting the client. But that will cause it to talk to the new Bigfix server and stop talking to the old one.
There's no possibility to have two agents installed on the same endpoint.
