With 2 layers of 3/4” ply glued you will have no perceptible sag even with a 200 lb person standing in the middle of the desk. Now if you and your best 200lb friend joins you in the middle and starts jumping, you might see a bit of sag but even then, probably not much. 1 1/2” ply is pretty darn strong.
Worst case scenario, you build it without the stiffener and add it later if you see a problem.

The sagulator mentioned by AandCstyle above is an excellent tool for providing this kind of information. You would have 1 1/2” of thickness with a solid wood edging. The “shelf span” is from the inside edge of wherever the boards are attached on either end.
