If you’re interested in a feature that is not currently provided by Oracle Cloud Infrastructure Security Zones, there are a few steps you can consider:

1. Contact Support: The first step is to contact Oracle support to verify if the feature is indeed not available or if it’s just not documented.

2. Submit Feedback: Oracle often provides a way for customers to submit feedback and feature requests. Make sure to articulate why this feature is important and how it would benefit users of the service.

3. Community Boards: Post your request on Oracle’s community forums. Sometimes, other community members have found workarounds, or your post could get the attention of Oracle’s development team.

4. Check Third-Party Solutions: If Oracle doesn’t provide the feature, look into third-party tools or services that may offer what you’re looking for. Make sure to validate their compatibility with Oracle Cloud Infrastructure.

5. Custom Development: As a last resort, consider developing the feature yourself. Oracle Cloud Infrastructure offers a variety of APIs and SDKs that might allow you to build what you need.
