These links should provide some insight:

https://infocenter.nordicsemi.com/topic/ug_nrf5340_dk/UG/dk/connector_if.html

Otherwise, the board files also show the default assignment of the pins.

I'm not entirely sure what you mean by "disable the default assignments". Changing the pins in the board files will change the pin assignment. On the DK there are also solder bridges which need to be cut or soldered for some pins:

Is there an InfoDoc on Nordic's website that shares the default pin assignments for each of Nordic's boards and how to disable the default pin assignments?

Hi,

P0.25 and P0.26 were UART0 pins on the deprecated nRF5340 PDK. On the normal DK (version 1.0.0 or higher) these pins should be usable as normal GPIOs.
