48Undervolting has been blocked by Dell since the automatic bios update which was pushed through via Windows update back early 2020. So many might have experienced thermal throttling within minutes of playing intensive games. I found a reddit with the solution to that problem, which allows you to unlock the ability to undervolt once more.
