* `-M` sets the vibration/rumble motor on/off; 0=on, 1=off
* `-s` sets the screen version; range 1 to 4. Note that an incorrect version will effectively disable your screen until you shut down the device.
* `-f` sets FP/BP for the screen driver
* `-t` sets Tearing effect FIX method of the ST7789 screen driver; range 0 to 3.
