Has anyone found a flat black that will not burnish when touched

What you want may not exist. Flat black paint works in part by leaving a
surface of randomly oriented particles or fibers. They are naturally
fragile, and can easily be polished off by contact, or filled with skin
oils.

Normally, if you want a surface to have low reflectivity you need to
modify it mechanically- some sort of bead blasting, cutting fine
grooves, etc. Then you apply the flat black paint. A prepared surface
like that is much more resistant to contact.
