Your desert King may be producing a main crop which will not ripen, but fall off if not pollinated by the fig wasp. If your un ripened figs are far enough along, which is to say, fully developed and ready to ripen, but have not yet ripened, you can remove and make fig jam. Bass has a good recipe, I believe, on his website Trees of Joy. If the figs are still small and not even close to ripening and you are running out of growing time, it's best to remove them.
