Hello,
During development you typically program the nRF52 directly from the development environment, e.g. if you have an nRF52840-DK:

If you have already developed an application and want to program directly, then I suggest having a SEGGER j-link (connect SWDCLK, SWDIO, VDD and GND to nRF52840), and use for instance "nrfjprog --program your_hex.hex" from a command line window:
