Shouldn't the build targets be added in the following pages as well?:

Boards name: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/board_names.html#boards_included_in_sdk-zephyr
Developing with nRF52 Series - https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf52/index.html

Also, I think, we would require a change log entry for this change - https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/releases/release-notes-changelog.html#nrf_desktop

nRF Desktop changes look good. We could consider adding a few comments (if needed I can add them through a separate PR).

Suggested small improvement to doc modifications too.
