Encrypt payload serialized by OnPhotonSerializeView

Options
Hello.

I need to encrypt the payload serialized with OnPhotonSerializeView. I've seen there're options to encrypt the whole udp datagram using EncryptionMode.DatagramEncryption, but does it also encrypt the serialized data? Also the PhotonNetwork.NetworkingClient.LoadBalancingPeer.IsEncryptionAvailable always shows true, as if the connection is always encrypted. Is it possible to disable the encryption?

Thanks.
