If you are talking about grafting or topworking with scion wood......yes, it is easy to do. It's done the same way as apples and/or pears. Collect the scion wood while dormant in the early spring, store it in the fridge and graft to the host tree as the tree is coming out of dormancy. I have 4 persimmon trees that were topworked in the spring of 2018 and already producing "cloned" fruit in the fall of 2019.
