Undervolt Nvidia GPU

Hello guys,

Does anybody know a solution to undervolt my Nvidia GPU. I have found threads to set a Power limit, but it is not the same as in windows, where I can limit voltage at a given frequency.

I also have found a GitHub thread where, people talk about the closed Voltage API in Nvidia cards after the 1000 series.

Does anybody have more information?

P.S. I have searched a few hours, haven’t found a satisfying solution yet.
