How to switch to I2C mode on STEVAL 25R3916B board?

Hi 

I am evaluating NFC function on your STEVAL 25R3916B board, but I would like to see how it works with the I2C interface. Currently, the default configuration is SPI.

I have downloaded STM32CubeIDE and STEVAL-25R3916B_V2.1.0 project code, but am not sure where should I put this definition "RFAL_USE_I2C", could you help me check where this macro needs to be placed?

Thanks 

Leo
