Why does my VDDC keep randomly resetting to 1.125? (RX 570 cards)

I set the VDDC to .950 or 1.000 or whatever then within a few hours, usually much less, something is resetting it back to stock level without me even touching anything. I'm using Wattman currently and maybe that is doing it somehow but I don't understand why. This also happens it I restart the mining software so it seems like it has something to do with changing of the GPU state level but I've set all of the voltages to the same value. I really need to solve this as there is 30-35 Watt difference per card.

Is there any utility that I can schedule to run on a timed basis that would allow me to set the VDDC? Or anyone have links to code to do that that I could roll my own utility? I would just set Claymore to restart once per hour or something but unfortunately it won't set VDDC for RX 5xx series cards.
