Looks like you haven't installed the nrfjprog properly. Do you have the Circuitpython binary with you?

Then try. If it doesn't work for you ( I can't think of any reason) Then you can flash it using JLink software directly.

You must be having the CircuitPython binary right! From your message what I understood is that you need help loading it to the board.
Can you explain what exactly you are trying to do?
If you are an absolute beginner then follow the instructions given the link:

make sure you have installed nrfjprog installed
