It's something that's in the genetic process, to drop smaller excess fruits so that ripening can happen with larger fruits. There's no way to stop it. I simply pick up all the dropped ones asap and keep them in a bowl in the house to ripen. Need to be fast or the ants will get there first. As for ripening on the tree, they still need longer. Mine are dropping fruit and none of the tree fruits are near ripe yet although they're all a lovely rose colour. Patience and keep the tree watered if you haven't had much rain.
