You can’t. The only case where this is possible is when the Bezier can be represented by a straight line. And then the parallel ‘Bezier’ can also be represented by a straight line. The situation is different for the broader class of rational Bezier curves. For example, these can represent circular arcs, and a parallel offset is just a concentric circular arc, also representable as a rational Bezier.
