Studio Neo, a separate program outside of Honey Select intended for use to generate images with the game's assets, does have a rendering function. You can manually set the output height and width, upsampling, alpha, lighting and shadows. It's not nearly as robust as the rendering options in say Daz3D or Blender, but that's because it's not a general purpose 3D application built to do ray tracing right out of the box.
It is more robust than just pressing F11 to take a screenshot in Honey Select.
Plus, let's be real here, this has nothing to do with aesthetics. There is a whole lot of crap here on F95Zone with people ineptly tossing a bunch of models into Daz3D, placing a spotlight right behind the camera, cranking up the ray-tracing high enough to make their computer cry for hours, all for a rendered end result that looks like absolute shit. There are also plenty of games made with Illusion assets that absolutely put all other games to shame with their asset usage, framing, posing, and shot composition. You don't need ray-traced lighting to make an aesthetically pleasing composition.
