Disable keyboard control

[Tshask]

The game forces me to define 2 (two!!) sets of keys to serve as keyboard controllers.

The game WILL NOT let you save settings unless you map all the keys for BOTH sets. You can't just leave them blank and save settings, the game will force you to define the keys.

So I have Controller 1 set to: WSAD for movement and UIJKBV for hits and select/start
I have Controller 2 set to some random keys just so the game pissess off and lets me save the settings

Problem: I don't need the second keyboard controller, like ever.

When I do videos or screenshots I need a lot of available keys on my keyboard to control slow motion speed, camera, AI ON/OFF, and tons of other options.

My characters are moving when I don't want them to, because so many keys are mapped to Tekken inputs. The keyboard control is ALWAYS ACTIVE. Both of them! Even when I'm already using the XBOX ONE controller and have no need for the keyboard to control my character.

So, is there a solution to this? Can I edit some config file and set the keyboard bindings to nothing, or is there perhaps a way to disable keyboard entirely for Tekken?
