In reply to vvs3693:
You can set the verbosity for a particular message by using its ID.
For classes not derived from uvm_report_object, which is mostly as the same a those derived from uvm_component, you need to set this using the global reporter, which is uvm_top.
Another option is to use a different context when reporting a message. And change the verbosity setting for that context. To use another context, you can do
where obj is another object derived from uvm_report_object. That could be another component like the agent or sequencer where this sequence is running, or you could construct another object
class my_item extends uvm_sequence_item;
static uvm_report_object log=new("my_item");
// use my_item::log.set_report_verbosity_level(level);
