How to disable full line code completion

I'm getting really frustrated with the full line AI code completion. It's rarely what I want and it breaks my flow. How do I disable it? I'm talking about the light gray text that appears after my cursor as I type. I want to keep the AI assistant and Junie. I've been searching for the answer for hours and only find things I've already tried and suggestions to change options that don't exist in the settings. Here are the things I've tried:

* Disable the _Full Line Code Completion_ plugin: This works, but the AI assitant plugin depends on it, so disabling this plugin also disables the AI assistant, which I want to keep.

* Settings → Editor → General → Inline Completion: I've disabled both _Enable local Full Line completion suggestions_ and _Enable cloud completion suggestions_, but still get the full line completion suggestions.

* Settings → Tools → AI Assistant: I've disabled _Enable cloud completion suggestions_, but still get them.

* Settings → Editor → General → Code Completion → Enable Full Line suggestions: Was suggested in a youtrack issue, but the settings must have changed because it doesn't exist there.
