My Godot 4 game is detecting touchpad events as if they were joypad events. How do I disable this?

Question

This is Godot 4 and, as dumb as it looks, this is the code:

func _input(event):
    print(event, " in device ", event.device)

When playing in debug mode, I see many events like this:

InputEventJoypadMotion: axis=1, axis_value=-0.35 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.01 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.35 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.01 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.01 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadButton: button_index=0, pressed=false, pressure=0.00 in device 0
InputEventJoypadButton: button_index=3, pressed=true, pressure=0.00 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.01 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.01 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.34 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.33 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.33 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0
InputEventJoypadMotion: axis=1, axis_value=-0.33 in device 0
InputEventJoypadMotion: axis=0, axis_value=-0.02 in device 0

(i.e. moving, moving, moving, slightly pressing the touchpad, moving, moving, moving...)

How do I prevent the touchpad from being recognized as a joypad / gamepad / etc? When I connect joypads (even a virtual one I'm developing), The result of this function:

Input.get_connected_joypads()

Is [0, some_id] where 0 stands for the touchpad and the other id corresponds to a physical joypad or a virtual pad.

In fact, I expect InputEventMouseMotion or InputEventMouseButton to be triggered from the touchpad. NOT my touchpad being recognized as a joypad in the game.

Any hint on this? I'd like to either:

• Fix whatever is causing my touchpad, in godot, to be recognized as a joypad instead. This is wrong to me, at least. Please: Do not suggest me about removing the 0. I'm not sure how stable doing that results.
• From Input.get_connected_joypads(), filter which devices do not belong to actual joypads (physical or virtual) and only keep the joypads.
