gpio pin as power source for other

Hello! Can I use one of the gpio pin as power source directly for other MC on my board (hx711 - ADC with current consumption in normal mode 1.5ma (from datasheet)). I understand I have to do it via transistor (or optocoupler) but my board is ready and I would like update my circuit a little (for power saving). chip nrf52832 app with radio, power consumption with ADC about 11ma, without 1-2ma (with radio, app base on buttonless dfu example from sdk).
