GPIO3 pin on DWM1001

So, I mistakenly wired my PCB to pin 30 (GPIO3) to use as a power led indicator (active low).
Unfortunately, I realized with the PCB in hand that GPIO3 is not in the list of available pins to control through PANS.
What I find surprising is, GPIO2 and GPIO3 in the DWM1001-DEV schematics are wired to 2 leds…

So, a few questions:

  • can I toggle GPIO3 manually? (dwm_gpio_cfg_output(3,0) didn’t seem to work)
  • can I somehow lower it if not using the UART feature?
  • why is GPIO2 controllable through the API, but GPIO3 is not?
  • why even list GPIO3 on the DWM1001 schematics if it’s not intended to be used?

Did you found anything about this? We used the GPIO3 and GPIO2 as uart pins of a gnss module and I can’t get anything.
