Change navigation keys for UI at runtime

Figured it out. I can create a custom EventSystem with the "StandaloneInputModule" script disabled then make my own script that is something like:

 void Update()
 {
     timer -= Time.deltaTime;
     if(timer > .0f)
         return;

     AxisEventData ad = new AxisEventData(EventSystem.current);

     if(Controls.Up())
         ad.moveDir = MoveDirection.Up;
     else if(Controls.Down())
         ad.moveDir = MoveDirection.Down;
     else if(Controls.Left())
         ad.moveDir = MoveDirection.Left;
     else if(Controls.Right())
         ad.moveDir = MoveDirection.Right;
     else
         return;
     
     ExecuteEvents.Execute(EventSystem.current.currentSelectedGameObject, ad, ExecuteEvents.moveHandler);
     
     timer = cooldown;
 }

To send events to the UI system without using the standard inputs.
