Default [Q] Force USB3 longer then 10 Minutes

Hi Guys, I was wondering if any of the DEVS have found a way to force the phone to stay on usb3 Mode and not switch back to USB2, i found it charges faster while tethering/ and while connected to a PC. I also noticed Tethering is smoother and better for some odd reason. Does anyone know how to tweak the setting?

Much Appreciated
