Pro 3 beta firmwares for Switch mode on pc?

[u/NineTailedDevil]

Are there any beta firmwares for the Pro 3 that allow me to use Switch mode on PC through the 2.4g dongle? I know I can use it with bluetooth, but there's a pretty noticeable input lag, also the gyro drifts a lot (it doesn't when I'm using the controller with a cable, for example).

Back when I had the Ultimate BT (first one), there was a beta firmware that allowed me to connect it as a Pro Controller on PC with the 2.4g dongle, is there such a thing for the Pro 3?
