Is it possible to avoid sending the joystick events to the operating system after being handled?

[BeayemX]

I boot my Pi to the command line and start a python script with cron to display system stats on the sensehat.
The joystick can be used to adjust some settings of the displayed pixels.

Due to the fact that the joystick events are being passed through to the command line it is possible to go through the bash history and execute these commands when pressing the joystick.

Therefore I would like to prevent all events coming from the joystick from being processed anywhere else on the system.

Is this possible?

It is certainly possible, but I don't know if this library exposes that functionality.
