Unless you have a suitable Bootloader installed - which would require an SWD programmer to get it in...

If you have a compatible STLink, it can be upgraded to JLink using an updater supplied by Segger.

You could also buy a Segger "JLink" (and JLink Edu)

Or one of many other different SWD programmers (check which are supported by OpenOCD)

Just search on eBay or AliExpress for "SWD Programmer" there are loads of them for under $10

Edit.

Just as a matter of interest, I just bought 2 different kinds of SWD programmer from eBay, one is a large STLink V2 which I hope is updatable to JLink using Seggers updater. The other is some sort of generic SWD programmer which appears to have an STM32 chip on it. (though precisely what that is, I won't know until it arrives)

(I already have 2 Nordic DKs and also several other SWD programmers, I'm just buying these to see what else is out in the market)

If you don't have the experience to get ocd working then get a JLink programmer which is designed to work out of the box and supported by Nordic and the recommended tools.

you can use the IDAP-Link to program it. With IDAP-Link, you don't even need openocd to flash it. The provided IDAPnRFProg commandline tool can flash both softdevice and you firmware at the same time, and dfu too out of the box.

i tried swd interface. I have st-link programmer. But open ocd is not getting configured. I really got stuck there. I am very new to linux as well nrf series controllers.

Use SWCLK and SWDIO to program. Remember to also power the board (VCC). The programmer might also need ground detect, so connect that to GND.

No you can't program it using UART
