How to use the DSI pins on the Portenta H7?

I've been searching how to use the display pins and connect to a screen but it is confusing to me. Most TFT screens I've seen use a flat 40pin for the clock, rgb, touch, etc. Maybe I need another type of display or a bridge in between?
What is the intended way to use the DSI pins on the portenta H7?

I found some LCD that use a MIPI interface. They are not cheap however and require more than 2 dsi lane if you want good resolution.
It might be a good choice if you want a 2" display in a compact project. Otherwise, I think the best option is to use something else.
