Can a custom 53003 message be created to replace the default?

When validating Conditional Access violations, the default 53003 error provides too much information about the client and login attempt. Is there a way to customize this error response so if a Conditional Access policy is violated a very generic response is provided to far end and not disclose so much information that can be used to further attempt compromise.

    @Jemison, Chad, Thanks for posting in Q&A. Based on my researching, currently, it is not possible to customize the conditional access error message yet. But your thought of security consideration is good. You can feedback in the following location to see if we can get this feature in the future.
