For uvm_info the default action is UVM_DISPLAY. If you want to take some other actions we can take it by id by using the method set_report_id_action. The other actions can be UVM_LOG, UVM_EXIT, UVM_NO_ACTION.
So now if the messages have to be turned off we can set action has UVM_NO_ACTION.
comp_handle.set_report_id_action("ID",UVM_NO_ACTION);
