No, it was expicitly stated in the series that KKG element isn't something you can learn, yet something you must born with. Dust Release doesn't fit here, since KKT was never said to have the same conditions, though I suspect there could be even more restrictions to it. And every Uchiha/Hyuha has their KKG since they were mostly breeding amongst themselves without allowing any foreign blood. Even if the latter appears, it doesn't necessary have to deprive the offspring from their KKG.
