Check with Pioneer if it matters. I am not sure choosing "no sub" actually blocks the signal to the subwoofer.
That adjustment on the receiver regulates the crossover setting to the mains. All "no sub" may actually do is allow the mains to run full range. The sub still may get the same signal as before.
