Allow to turn off touchpad built-in in a media keyboard

[AlexaBalu]

I own "MICROSOFT All-in-One Media" keyboard - https://www.microsoft.com/en-us/d/microsoft-all-in-one-media-keyboard/8ttd9j9jnsf0

The problem with it is that touchpad there is interpreted as left stick which is constantly pressed in right/top direction. Also even If I connect first external mouse then this keyboard (which looks fine, since touchpad is ignored when testing configuration), within the game the external mouse is dropped and replaced by this in-built touchpad (which of course has constantly pressed right/top direction).

The request is to allow for turning off the built-in touchpads. Anyway fixing that "constantly pressed right/top directions" issue also would be nice, but it would require buying that keyboard. Probably dropped external mouse also is a bug.

External mouse was connected via independent dedicated USB adapter and keyboard with touch pad had own dedicated USB adapter.
