Is there a one click way to make a kindle fire a pure Android device?

For non-technical users, is a one click way to get rid of the amazon stuff & install stock Android?

I am trying to help a friend on another continent who has a kindle fire 7 running OS v 5.6.8 (auto-updated just a few days ago, which looks like it might be a problem).

Solutions seem to involve downloading scripts to a PC, then using Android Studio to side-load the scripts to the kindle, then running them, which would beyond my friend, even with assistance – even if they had a PC, which they do not (nor access to one), just the kindle fire.

Does anyone know of a one-click solution, or something close to it, involving only the kindle fire (7 OS 5.6.8)?
