Hello,

Yes, no problem. Though the nRF52833 don't have a QSPI interface, so just make sure you connect it using normal SPI. The nRF Connect SDK have supported for NOR flash.

Also, be aware of this note when you do the layout: https://docs.nordicsemi.com/bundle/ps_nrf52833/page/pin.html#ariaid-title3 

QFN40: Note: If SPIM0, SPIM1, or SPIM2 is used with 8 Mbps data rate, the recommended GPIOs for the clock signal (SCK) are P1.09, P0.04, and P0.31. 
WLCSP: If SPIM0, SPIM1, or SPIM2 is used with 8 Mbps data rate, the recommended GPIOs for the clock signal (SCK) are P0.27, P1.08, P0.04, and P1.09.
