This is the solution, you don't need to uninstall him at all.
Here is the edit version:
Go to data\DAZ 3D\Genesis 8\Male\Morphs\Hinkypunk\Renshaw\ in your library, open Renshaw Pupil Morph.dsf with a text editor. Scroll down to line 32, change "value" : 1, to "value" : 0, and save it. That should fix it, for the DIYers
or within Daz Studio:
Open the Renshaw Pupil Morph Dial
You need to change the default value for the morph and set it to 0. You can do this by changing the morph properties (open them with the cogwheel on the slider) and then resaving the morph asset, or by editing the morph data file directly.
