You don't use UICR for that. 
 You use either sdk_config.h or the custom board header file for your board (when using NRF SDK).

You simply cannot do that - the application has full control over which gpio pin has what digital function assigned to. Simply by putting the correct magic number in the peripherial register (PSEL.XXX).
