Open settings, and search for"Gemini" from the search bar. That’s the only way I was able to get to anything Gemini related. I turned off it’s access to everything from there, then the last setting was to switch back to assistant which appears to have turned Gemini off, but who knows (hence disabling it’s access to everything anyway).
Purely hypothetically speaking, but, what if someone had their own private Dyson Sphere generating electricity? (Asking for a friend.)
