Hello,
There are some of our radios that can support it , nonetheless, we currently do not have any software to enable BLE Mesh .
Still, you could work with a third party supplier and get a Bluetooth Mesh Stack and have it running or you could check and verify if some open source has the support for some of our parts (like the Bluetooth Mesh software that is part of Zephyr).
You can also check with the professional services in this link.
I apologize for the inconvenience this might cause you.
Regards
