Yes and no.
You need either the DK or a J-Link debug probe in addition to the dongle for the above flashing method - as described.

But even if I have the nrf82540 USB dongle device, do I still need the J-Link debug probe ? and i want to flash the .hex file, will the dongle alone be sufficient?

i just have a small question. If I generate the .hex file for the nRF52840 and flash it using DFU via nRF Connect, Then i don't require for J-Link or SWD?
That is correct.
