Can the NFC port be disabled and used as GPIO?

[DX_HK]

I am using nRF52840/nRF52833 (raytac module, original board).
With the current nRF Connect SDK, is it possible to disable NFC and use ports (P0.09, P0.10) as GPIO?

I am trying to assign P0.09 to I2C SCL, but it is not available as GPIO.

I have enabled the following parameter in Kconfig.
I understand this is deprecated:

CONFIG_NFCT_PINS_AS_GPIOS=y

Since it is recommended to edit the DTS, I added the following to the overlay:

&uicr {
nfct-pins-as-gpios;
};

However, none of the settings are effective and P0.09 remains Hi-Z.
Please tell me the correct setting method.

Sorry, it was my mistake.
The reason was that my brain was a lower-level compatible version of Meerkat.
The connection on the P0.09 board had been lost.

Hi, Kanai-san.

I'm happy to hear you figured it out.

As a mention, when looking at the nRF52840's pin assignments list, you'll see that the P0.09 and P0.10 GPIOs are only recommended to be used for low frequency I/O.

Best regards,
Mathias
