I tried it out both ways. Turning off the parts in the GP didn't help, because that shell is needed for the color, since it uses the materials of her torso. [1]
Turning of the related parts on the wet skin shell can at least be utilized some way:

I'll keep a lookout for better solutions.
I'm positively sure, I've seen AVs with wet skin and things working out with the genitals as well.
Sadly, most devs have better things to do, than teach their knowledge. Well, rightfully so, since this shit is time-consuming as fuck.
Before I tried myself out in DAZ, I had no sensibility for this whole rats-tail of shit everything seems to keep attached.
