Xbox controller, disable left analogue stick from backwards

Unity Engine
1

Tried to get the post of it in the title, but I was hoping someone out there would know how to disable using ‘back’ or ‘down’ of the left analogue, for the joystick on the y axis? Its for a spaceship and if you hold the analogue down the ship goes behind the camera, so I want to disable it all together?

set if vertical axis is negative, then it to equals zero.

void Update(){
var v = Input.GetAxis("Vertical");
if(v <= 0)
v = 0;
}

it’s trivial really.

Works, thank you. not sure why I didn’t think about that, long day.
Thank you
