I'm trying to find any documentation for the pinout of Nucleo-H755ZI-Q. The GPIO pins for CN12 and CN11 are written on the board but not CN7, CN10, CN8, CN9.
How can I know which GPIO pins are connected to which pin on this connector?

When I hold my board with CN14 (RJ-45) facing downwards, I find the labelling CN11 and CN1 above the pin rows without connectors. Directly to the left of CN12 is CN7, to the right below CN11 is CN8, along the CN8 you will find a gap with CN9 and on the other side at the very bottom at the end of the black double-row connector is CN10. Do you see it?

I think you misunderstood my question. What I would like to know, is which of the pins in CN7, CN10, CN8, CN9 are connected to which GPIO pin, like in this pinout for NUCLEO H743ZI.
(NUCLEO H743ZI has the same board as Nucleo-H755ZI-Q, but the pinout is different. I checked with a voltmeter.)

Ah, but your picture is not from an official source of STMicroelectronics.
However, you can find the GPIO assignment on the back of the NUCLEO board as well as on the front. If you prefer to look in the documentation, you can find the pin assignment of the connectors in the UM2408 or the schematics, for example.
