where is UARTE configuration in sdk_config.h?

According to this doc (for SDK15.3/UART):

infocenter.nordicsemi.com/index.jsp

It seems I can follow the steps to enable UARTE. But where is that "#ifdef NRF52...." section? Or am I suppose to type it in?
Am I looking at the wrong document?

#ifdef NRF52

#define UART0_USE_EASY_DMA false

#define UART_EASY_DMA_SUPPORT 1

#define UART_LEGACY_SUPPORT 1

#endif //NRF52

Never mind. It seems I can completely ignore sdk_conf,h.

I simply called nrfx_uarte_init() and supplied a handler. Then both nrfx_uarte_tx() and nrfx_uarte_rx() works. Am I on the right path or did I missed something?
