Provisioning server settings vvx450

[EPWxDan]

Trying to provision some Polycom vvx450's but Zero Touch doesn't seem to be working. When I try and apply the changes manually, there aren't any changes being made when I perform a factory reset.

I don't see in the web interface where I can update the Provisioning server for assisted provisioning . Does anyone know where to set the provisioning server in this interface? Or how to provision vvx450's? Am I missing something? I have some vvx250's that were a breeze, and I assumed these would be the same.
