I'll share what little I figured out by messing about. Once you enter the game there should be a panel full of buttons on top of the screen. After that enter the level of your choice. I'll prefer the gallery as all actors are instanced (created) upon loading the level, standing way off camera when not in a scene. For the most ease we want use thek "Object Explorer", so click that.

This should bring up a panel like this:
Only "Handler should be visible at first. Clicking on
the triangles, navigate to Level/SpawnedObjects.This should give you a list of characters. Pick the one(s) you want to modify. From there under "GXF Root" should be several items. The two folders that concern us are "GFX" and "HGFX".
HGFX specifically affects models in sex scenes while GFX affects everything else. They are independent, so if you'll need to manually change both if you want them to match.
And now for a hiccup in our escapades. I noticed that some items despite being being checked (the box beside the item is green instead of black) are still invisible. Clicking on the offending item's name opens the inspector. There a list of items lay under widgets. Clicking "SkinnedMeshrenderer" brings us to this screen.

At first glace, it appears that changing the
Render.enabled
and
Render.isVisible
to true before hitting the "Update displayed values" button should ammend our issue. However, the values simply reset. It seems to only affect this particular widget on all characters and the bukkake system widget (reached by clicking a female actor's GFX or HGFX folder) on Onyx specifically. Additionally C# scripting is disabled due to an incompatibility error. I'll experiment with the additional recommended plugins to see if the two issues are related.
