USB-C P/D hardware design question 

I'm quite lost in the weeds of USB Type-C P/D and alt mode negotiation, so hopefully someone can help me out :)

I'm designing a simple sink, that needs to request power (not picky about voltages at all, but requesting max available would be ideal), and gets the DisplayPort signal out

From what I can see most chips don't use this configuration by default, and need either config/firmware flashing through proprietary tooling (eww), or an external controller, and there's a bunch of different (open source) firmware implementations for stm32/arduino/rp2040, with varying functionality.

What's the easiest way to get power + displayport, with the simplest (none) extra flashing steps or chips?

Ideally I could re-use a Framework top-cover too, but they're a bit too expensive to buy a replacement just for this (~100 eur). Could be marketed as a great upgrade path to the newer CNC top-cover though, so might just send Framework a message about their developer program stuff

But then I can design something really nice with the same lcd my Framework has (3:2, 2K resolution) instead of the 1080p 14" ready-built options on the market

just have to design the housing myself, eDP to USB-C boards are easy to find on aliexpress too

I went from "ooh these portable external monitors are great, I want one" to "I can make this myself, even better" and now I have a Project
