I found the statement that hardware appliances don't have the option to disable encryption:
"Only the new VMs deployed post 6.7 have the options to determine if they want to use this or not.".
Starting ClearPass 6.7 there was a switch to full-disk encryption with 256-bit encryption, which more or less obsoletes the information that you found.
If you need a legally binding statement, please work with your local Aruba SE.
