This would be more for the phone manufacture, I think, to see what is possible.
I did see this post:
Can i disable call transfer for a single extension - Distro Discussion & Help - FreePBX Community Forums
If the transfers occurring are using the context from-internal-xfer, you can take a look at it and see if you can add it in extensions_custom.conf or override it completely with extensions_override.conf, with some sort of check for the specific use case and cause the xfer to fail.
For FreePBX to do this, you will need some custom dialplan.
