No, unfortunately the game has no API. You can however build something like an Arduino key presser. The ATmega32U4 microcontroller is able to send key presses and be viewed by computers as a real keyboard or game pad. I built an application the displays UDP data to a commentator. They can then interact with the app, and if they click on a driver it will send commands to the Arduino to send the key presses needed to switch to the driver on track while spectating. You could do something similar with MFD menu bottoms. Not sure if emulated (by software alone) key presses will work with this game, which is why I used the Arduino.
