rf-nano from Keywish

Is there a possibility to load a bootloader on the Keywish rf-nano. There are no normal contactpoints as on the other boards. While this is a very usefull and promising board, many people like me will upload an erronious program as i did and break the internal bootloader unintentionally.

It seems that I can rephrase my question in a more general way: How to re-flash an Arduino Nano bootloader and the answer appears to be: https://www.circuitstoday.com/arduino-nano-tutorial-pinout-schematics if I am right?
