I'm in the same boat - my work uses chromebooks.

I got frustrated earlier this week, trying to remove AI suggestions from Google on my work account. It's set up in such a way that I can't opt out. Search for ways to remove AI from your results, and all the tutorials say to "Click the lab button" to disable AI.

I looked on my Google page - there is no "lab" button.

I looked up trouble-shooting for "no lab button," and attempted to follow a direct link to the controls it's supposed to provide.

Apparently, since my account is managed by a company, I don't have access to permissions... including the permission to remove AI results. Fuck.

Long story short, although I really wanted to throw my work laptop into a fire, I instead decided to change my default search engine to DuckDuckGo.

I can't escape the Google environment entirely, but at least I can still use a search engine that lets me opt out of automatically generating AI crap.
