The Runway Awareness and Advisory System (RAAS) on the 737 MAX is a great Situational Awareness tool. However; I experienced what appears to be a design flaw in its triggers for approaching crossing runways.During takeoff on ZZZ Runway XX; Runway XXR crosses Runway XX about 700-800 feet from the threshold. Following FOM Guidance setting the thrust for takeoff; RAAS alerted us with 'Approaching Runway XXR' during a critical time in the takeoff roll. Coordination between the Pilot Flying and Pilot Monitoring for setting takeoff thrust is absolutely critical and the distraction of an unnecessary warning compromises safety. The trigger for that particular warning to be silenced is 40 knots ground speed or greater. The thrust lever angle/setting or thrust mode in TOGA should also cancel the warning.
