You can't remove the handles, but you can manipulate them by pressing and holding ALT and grabbing the handle point and move it.
This will alter the shape though.
But why would you want to remove a handle since you turn the created shape into a path or shape.
Well, thank you. I do not know everything about Photoshop yet. I study the functional. And, I thought it was an elementary operation, but I did not find how to do it and asked for help. It is now clear. Thanks again!
