Removing Multiline Voicemail Button on 53xx

System 3300 Mxe, running Software Version 9.0.3.15
Hi is there a way to remove a Message Waiting Button from a 53xx without user clearing VM's.

Problem I have is both the user with the Message Waiting key and the Voicemail Owner are out of office.

The message must be inactive before changes can be made
