Hi, you need to give more detailed info about what kind of display this is. Lfs supports only normal monitors and VR headsets natively, however...
Quick google search shows me that a CM2 screen is just a raw display with its display controler, that usualy needs to be connected to a microcontroler with specific firmware via SPI or i2C bus which sends data to it. Then through virtual serial port (over usb connection) a microcontroler gets the actual data from a special app on PC. For example SimHub is able to receive telemetry from LFS once it is configured in cfg.txt to output outSim or outGauge packets, through LFS internal inSim protocol that utilizes UDP or TCP connection. So in principle, one can say that LFS does "support" such displays and it is possible to send data like car angles, velocity, tyre and engine temps, speed, gear, rpm and much more, but it's not such a straight forward task. In moza wheels I guess their main microcontroler stm32F407 is able to do this feature as well along with handling DirectInput - axis, buttons and ffb.
So look into SimHub program and see if it supports your display. If not, you could even use your phone and SimHub can send telemetry from LFS over your home wi-fi to it and display data in a very convenient way to look like car dash display. They have many different nice looking plugins and it works great, but you need to figure out a way how to hold your phone above your wheel base.
