Specifying "No Camber" will not give you a stiffer joist, just one that is
fabricated flatter. If you really want a stiffer joist you need to specify
either a minimum moment of inertia or a maximum deflection.
Additionally, specifying a non-standard camber will add significantly to both
the price and the delivery time for the joists.
