Yeah, without the correct schematic...
Can you advise on how to find out where the pins are actually going to? Can I just probe them all from the MCU pins to the headers to find out which is which? It now really seem that the schematic is completely different from the V1.0. one, at least for the DRIVER headers, since there are some pins that are correct and I can control them, like the LED, I2C header or HardwareSerial

Sir, I have a question "How can I find out which pins on the Octopus Pro v1.0.1 board correspond to which headers, without the correct schematic?" I would be very happy if you could let me know, thanks

So if you have the board, you can check in the repository to see if they match, it is fairly 'easy' if you have the schematic etc.
As you can possibly make a little sketch that you can probe the ports using digitalWrite() etc, then using leds, multimeters etc, you would probably be able to figure out if they are at the correct pins.
