I said the Dev Kit - not the Dongle!

😃

EDIT

It's not clear what you mean by "program this board":

"program" as in "develop code for"
"program" as in "load code onto"

For loading (aka "burning") the code into the chip, you will need either an SWD debug interface (eg, JLink) or a bootloader.

With a bootloader, you would still need the debug interface to initially load the bootloader itself.

I checked the NRF52840 dongle as example to make my schematic but what I want to know is it will be possible to direclty code on segger and upload on the nrf52840 because on the dongle, I have to use the NFC programmer.

What does the nRF52840 Product Specification tell you?

Look at the nRF52840 Dev Kit schematics for an example ...
