following on from this comment, it is possible to get it turned off for a Workspace Suite Account
- contact support (
?
button from admin view) - ask the first person to connect you to
Workspace Support
(otherwise you'll get some made-up bullshit from a person trying to buy time or Case Success or whatever, simply because they don't have the privileges to do what you're asking) - tell the referred-to person that you want to enable controls for "Gemini for Google Workspace" (optionally adding that you have already disabled "Gemini App")
hopefully you spend less time on this than the 40-something minutes I had to (a lot of which was spent watching some poor support bastard start-stop typing for minutes at a time because they didn't know how to respond to my request)
