How can I hide certain things from agents?

[kmdot]

Is their a way I can hide certain attributes, such as close, from a certain agent group?

Is their a way that i can set it so that agents that are no locked to a ticket cant make changes to that ticket?

Can i stop agents been able to self assign tickets, ie, lock.

Thanks
