I know there is many libraries such as manifold support subtract (difference) , union intersect of two 3ds
is there any way to do it in direct3d or direct2d?

The intent is for the application to provide information on how to render a scene, and Direct3D will render the scene. Any transformations and other manipulations are separate. For example, the Windows SDK provided library for transformations is DirectXMath.
For this specific question, no there is nothing that I know of in Direct3D to do this. I don't believe there is anything in DirectXMath either. Either way, if this is about removing common points from a set, or removing the volume of one shape from another then I suggest you pick up a mathematics book or two.
