These also have a GPIO number, so technically you can address them like any other GPIO. However, note that normally, these pins are connected to the internal flash of the module/chip/devboard you have; in that case, reconfiguring them as a GPIO will likely crash your program. Check the datasheet of...

hi What is Use of following IO pins? can they be used for normal GPIO operation?
