Currently, the ID EEPROM is always write protected. One needs a pull down the EEPROM pin with a needle probe or similar to disable the write protection. The schematic segment located at https://github.com/raspberrypi/hats/blob/master/eeprom-circuit.png shows how a jumper could be used to enable programming of the ID EEPROM after soldering it to the wuhat. Even if the pin header is not populated, the availability of the pads would ease programming.
