Dispersion comes from your swing path and clubhead not being in the same place at the same time so when you make contact, there is a right or left bias to your ball flight.  There is no setting, per se, that will correct dispersion.  If you are looking for which setting to use for a more right to left ball flight, more loft will help the curvature of the ball flight (and initial direction) and the lie angle is more likely to  influence the initial direction off the clubface.  It is the combination of the two that will help you achieve the most right to left ball flight (RH).
