CM4 camera/display -- direct connection - eviltoast

I am about to start putting together the DreamDeck – modular deck, which core module will be built around Raspi CM4. Thus, I am looking for a way to connect essential peripherals (a touchscreen and a camera) directly to CM4, not through I/O board.

So far, I only found products that use I/O board as an intermediary. Perhaps someone can point me towards a solution?
