Turn ray off is quite ambiguous statement.

Turn off visibility from those rays? You can do that by iterating over
objects and modifying visibility flag accordingly. Knowing that you don't
use Blender anyway, that would be a proper way to go to achieve this with
Cycles core code.

Turn off as in disable GI for those rays? This can be done using bounces
limit in integrator settings.

Value of 0 for BPT is malicious. Consider you've got diffuse cube lit by a
lamp. Now, when you set diffuse samples to 0, do you really expect to see
completely black cube? This idea id didn't get at all.
