It worked by defining (just adding) an macro (rather variable) CONFIG_NFCT_PINS_AS_GPIOS in system_nrf52840.c

You can see the Infocenter, specifically these links (UICR and NFC pin configuration), for how to set the NFC pins as regular GPIOs.

Best regards,

SmartBASIC is a Laird thing; nothing to do with Nordic - so you'd have to ask Laird about that.

If you don't want to use SmartBasic, I guess you'd have to do a full chip erase and then just treat it as a standard nRF52840.

But, again, you'd need to check with Laird to be sure ...
