Please do not mark your answer with Suggest as Answer as this will close the ticket.

What version the nRF9160 DK are you using? What version of nRF Connect SDK are you using?

From the nRF9160 DK board control chapter in the nRF9160 DK User Guide.

Why do I need to configure this? For SPI or CS Signal? No sample code is doing that.
I am using P0.13 (SCK), P0.12 (MISO), P0.11(MOSI) & P0. 21(CS)
Sorry if it's too basic.
Secondly, can I configure it using nrf9160dk_nrf9160ns.overlay?

Hello,

Have you configured the EXT_MEM_CTRL on the Board Controller? More informatiion can be found in the Board Controller chapter under Working with nRF91 series, which is further explained in the board controller chapter of nRF9160 board definition in Zephyr.

Kind regards,
Øyvind
