The USB-C is only connected to the CB1/CM4 high density connector.

The STM32G0B1 USB connection is directly connected to the USB hub chip for the CB1/CM4.

and where are you getting this information? there is no schematic so therefore no way to really know

If you load Klipper onto the M8P/M4P, you will never see the M8P/M4P on the USB-C port; you will from the CB1/CM4.

Typically an RPi has four USB ports; the M8P/M4P has two plus a USB header behind the two USB ports. This leaves one that you always see the M8P/M4P on when doing a lsusb on the CB1/CM4, also displayed are the physical connection numbers 1-4, the M8P/M4P will always be on the same physical connection.

What does that mean? can the board be used with external Raspberry Pi or not?

Set up the M8P firmware for UART, the M8P USB option can not be accessed since it is hardwired to the CB1/CM4 high density connector with no external connections.

Go with the Octopus Pro (for eight drivers) or SKR3 (for five drivers), these are a better fit for an Raspberry Pi 3/4.

you have to use the display pins or some extra motor driver pins and set the firmware to use UART then you can connect the pi to manta, your probably better off buying a cm4 or cb1

That is basically the idea, the board wasn't designed to be used without a CB1/CM4. To be able to currently fully use the GPIO, Camera, DSI you would need to use a CM4.
