The only way PPE could be bypassed is for you to put the panel in an "Electrically Safe Work Position" aka shut it off prior to resetting the breaker! If it must be done "live" you would need your FR clothing, class 00 rubber gloves with leather protectors, and depending on the arc flash study, a 4 cal. face shield.
In fact, according to NFPA 70E 130.1, you have to put it in an electrically safe work condition unless it introduces additional or increased hazard or it is infeasible to do so.
So, to reset the breaker, you have to de-energize the control panel, suit up in your FR gear and gloves, test the circuit to ensure it is de-energized, then reset the breaker and re-energize the panel. If the disconnect to de-energize is not within view, don't forget to apply LOTO procedures.
Sure makes it worthwhile to investigate why the breaker tripped first. If it trips again, you have to start over.
