I do not have an example on this but I can guide you to this video made by Badreddine where he explains how to set another display on a STM32H7B3 disco board. In your case I would advise to start from the application template of the STm32F429 disco board available in TouchGFX Designer, or use it as source of inspiration for your MCU configuration in CubeMX.
