orange pi cm5 module & base board, activate and set interfaces

[MattiaGrigoli]

Hi, i'm looking for a way to activate some interface (like i2c, UART, CAN) in my orange pi cm5 with base board from orange pi but i can't find anything on it.
i'm using ubuntu version 22 (obviusly the joshua one).
i've looked through the device tree overlays but for my board i don't find anything useful, maybe i can also use the rk3588 one? (even if my processor is rk3588s)
and how do i use these interfaces? with the 12 pin connector under the board?
it'll be very helpful if you can help me with this issue, because for every board there's something but this one there's almost nothing.
thank you
