On my site, if user refuses to use cookies, I block tracking of Google Analytics using:

window['ga-disable-UA-XXXXXX-X'] = true;

And I delete cookies about Google Analytics (_ga, _gid, and _gat) using:

Cookies.remove from js-cookie

Everything works so far.

However when I navigate on my site I saw a weird cookie: _gali. What's this ? How to disable it ?
