Hi,

Yes, you can use the J-Link debugger to program the board via the SWD interface. Please take a look at this documentation:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/custom/programming_custom_board.html 

You would need the SEGGER J-Link software pack installed.

Also, you would need the nrf Command Line Tools which has the nrfjprog required for flashing the device. You could also install the nRFUtil.

Please take a look at this ticket as well:  Custom board considerations with a nRF5340 for flashing/debugging
