No, the only thing i can do is ''wash the history of that'' but private bitcoin transactions can't be done right now and if is im not aware, but you will have a way soon, but that doesn't grant that people will adopt that tool, because as i see bitcoiners think anything that isn't bitcoin is a shitcoin so i don't most will comply. But you will will not be transacting bitcoin, you will move that bitcoin with another coin...
