Is it possible to disable the 3.3V for the QWIIC interface?
(Background is the “evil PWR LEDs” of some QWIIC boards, see QWIIC board and power LEDs .)
nRF9151 feather - disable power for QWIIC interface?
Not in v1. I would agree that could be useful for managing phantom power draw. Not sure if there are any spare GPIOs on the 9151 but there should be some on the nPM1300
