No noise in Penumbra SMRT Samples at Zero?

Trying to understand why disabling virtual shadow map samples with directional lights has no effect on the noise.

Running this command: r.Shadow.Virtual.SMRT.SamplesPerRayDirectional

I increased the directional light source angle to get a wide penumbra and it is very clean and nice. I want to see how low I can take the samples before it gets too noisy, and yet, setting SMRT rays to Zero looks exactly the same as 8 rays.

So, what else could be contributing to such nice shadows?
Could it be the Scalability settings overriding the commands?

I think I solved it, was using Hardware Raytracing and wasn’t aware that Virtual Shadow maps aren’t used with Hardware Raytracing.
