Diag level of testsb on M9000

Is there a way to set the diagnostics level used by testsb, i.e for a board that is not a part of any domain (Eg min vs max) -I can only find how to set the diagnostics level for the hardware in an actual domain using setdomainmode.  If the diagnostics level of testsb cannot be controlled, what would be the effective level of diagnostics... Or does is it not comparable to any domain diagnostics level?

P.S. AS per the Question title - if relevant, my question is specifically about an M9000
