How do I disable AI suggestions in Apple Mail?

You can go to Settings-> Apps-> Mail and then select Apple Intelligence & Siri. From there you can toggle what AI has access to for the Mail app. You can also turn off contact photos and message summaries from that same area.

A thoughtful email was received and when I went to reply, Apple intelligence already had a suggested reply that said: "Sounds profound, I agree." A completely inappropriate response. I do not want AI suggestions like this and going to Apple Mail settings I see no way to control AI in Mail. So I went to System Settings and the top choice allows me to turn off Apple Intelligence which when I did it also displayed a message that writing "helps" be off too. I hope that works for emails. The message seemed to be an all-or-nothing AI choice except for SIRI; maybe there's a way to choose where AI can be available when wanted?
