Disable Track Pad on Magic Keyboard (Ipad)

When I type using my Magic Keyboard, I often accidentally touch the Track Pad and the cursor moves and messes up what I'm doing. I would like to disable the Track Pad when an external mouse is connected. This can be done on my MacBook Pro 14 (2021), but I cannot seem to find a way to do it on the Magic Keyboard. IF this is NOT a function, it should be as it is very annoying when this happens.
