Undervolting Laptop Gpu

I have a Dell Inspiron 15 7567 (Killer gaming laptop for the price btw +++) and I currently have my cpu undervolted by -0.130v in IETU. I want to undervolt my gpu as well for temps but I cant use MSI Afterburner as its incompatible. Would anyone who uses NZXT Cam help me to undervolt my Gtx 1050 ti? Cheers.
