Suppress the prompt "You cannot access portions of this document because it was encrypted..."

I am adding Secret encryption to a field and I want to suppress the Warning/Prompt to non key holders that reads “You cannot access portions of this document because it was encrypted and you do not have any of the keys”. I have tried a few things including using a different form for the non-key holding users that doesn’t include the encrypted field but it still displays the same prompt. Any suggestions on how I could suppress this warning?

You can’t; at least not in any way I can imagine. If this behavior is unacceptable to your app UI, then you can always redesign the app so that the encrypted data is stored in another db, and some forms retrieve/display the data while other forms don’t. (Note that you may not need the encryption in this case; ACL settings will do.)
