DXO PureRaw 3 preferred settings

Hello,

I'm creating this topic because I've been wondering for some time about the use of the Lens Sharpness parameter in DXO PureRaw3. I tested the off mode then in low, normal and high and I find that on the chosen image (image slightly noisy) the best result obtained is without the activation of sharpness of the lens in the software.

I would like to know if you use the lens sharpening mode and if so how? Thank you in advance for your feedback.
