Hmm i'm not sure if that's really what you were looking for. The settings of chrome are stored inside your home folder /home/$username/.config/chrome (or /home/$username/.config/google-chrome - im not sure). Those configs in your home never get touched by the package manager (even with purge option). So they are always still there after uninstalling the application. Thats the same on Ubuntu, Fedora, Solus, ... you name it. You could just have renamed/removed that folder in your /home/$username/.config. By launching chrome the next time, it would have had default settings (and the folder would be created again). Same goes for other programs by the way (like firefox, gedit, etc - settings=config is stored in your home.... 😀
