If you're referring to InputControlScheme ( https://docs.unity3d.com/Packages/[email protected]/api/UnityEngine.InputSystem.InputControlScheme.html ) then you'll need a custom class to monitor the scheme independent of the device or a 3rd party tool to get it to work.

I tried the custom class route through replacing the PlayerInputManager component. However, I have yet to get it to work. A full scene that includes that custom class (and hopefully will eventually also include fixes for getting it fully working) are posted at https://discussions.unity.com/t/2-players-1-keyboard-custom-playerinputmanager-to-handle-sharing-a-device-with-multiple-players/1535785
