Sensing regulator for 24v BLD series alternators

I have a BLD2130GH 12v Alternator which seem to be doing just what I want. Is there a 24V equivalent regulator with the lamp driver and sensing terminal?

I have noticed that there are 24V BLD's that have both but they also have a TX/RX terminal, maybe these can be used but will they operate without the TX/RX terminal connected?
