You cannot eliminate Bokeh without eliminating the out of focus portions of the picture. The Bokeh can either look nice, or not so nice, and is determined in part by the mechanical construction of the lens (aperture blades) and to the extent that certain aberations (I believe spherical is the main culprit) have been controlled.
