XPS 15-9570, bring back the 78°C GPU set point

I am requesting that Dell brings back the previous 78C set-point for GPU throttling.  Setting the GPU to throttle at 74C is just way too low and doesn't allow the 1050ti to run at reasonable rates.  If Dell won't allow this, then allow us to go back to bios 1.3.0 or 1.2.2 so we can use our laptop.
