Here are some preliminary mods to get you started!
I haven't tested this much due to time, but this is a simple VID mod for +300mV. For additional voltage you can also add the voltage sense mod which will allow you to set any desired voltage. I have run into some protection issues (OVP/OCP) above 1.40v. After reading the datasheet it looks like there are a few more mods to try, but this PWM is notorious for multiple layers of protection.
Based on my testing with EPower and unlimited voltage potential, I have concluded that there is little to no voltage scaling on water past 1.35v ish. Thus I believe the mods I have outlined here will be able to max out the card for water cooling. If you are planning on competing in the extreme category with a reference PCB, you will need further mods to max out the card. Based on one quick LN2 session, I observed a maximum scaling potential of about 1.6v.
