Hi - if you mean that you would like a greater number of triangles on the BET mesh surface - this is fixed in the BET program. You would need to edit the source code to increase this, but there would be no guarantee that the BET surface fitting would still work as BET is highly tuned for the fixed number of vertices that it uses. Cheers.
