How to switch HDMI and MIPI LCD on STM32MP157C-DK2?

I test the prebuilt image on dk2 board. Sometimes the GUI application on MIPI LCD, and other time on HDMI. I checked the datasheet, HDMI and MIPI use same LTDC conctoller. So I am confused, Does it support same time display on HDMI and MIPI? If doesn't support, how to switch HDMI and MIPI ?

Please have a look to https://wiki.st.com/stm32mpu/wiki/How_to_display_on_HDMI, the switch between the two interfaces (DSI or LTDC=>HDMI) is pure SW choice.
