I solved the above but now have the following:

nrfutil pkg generate --hw-version 52 --sd-req=0x00 \
        --application zephyr.hex \
        --application-version 1 blinky.zip

I just need a way to program the dongle from the command line (Ubuntu) if there is another solution I would be happy with that.

I was able to find and install nrfuti. however I cannot get it to work..

Under Ubuntu I attempted to program my nrf52840 dongle with the follow command:

"$ nrfutil dfu usb-serial --package zephyr.hex --port /dev/ttyACM0

The zephyr.hex file was created by a west build command; a file command returns:

file zephyr.hex
zephyr.hex: ASCII text, with CRLF line terminators
