Can Opt-in AI Features be disabled after activation?

Hello,

We are currently enabling some of the new Artificial Intelligence features in Oracle Fusion Cloud, and a customer has asked the following:

Once an AI-related Opt-in Feature is activated via Setup and Maintenance (e.g., "Create Negotiation Cover Page with Generative AI"),
is it possible to disable or roll it back later if needed?

The customer wants to confirm whether the activation is reversible, or if it's permanent within the environment (TEST or PROD).

We would really appreciate any official guidance or experience from the community on this.

Thank you!
