No, no, no. The standards bodies very carefully and purposefully avoid specifying the hardware in their attempts to standardize NFV.
Cue, here is a quote from one of those documents you reference: NFV-INF003v031-Compute_Domain.pdf
In section 4.4.1.1 Processor & Accelerators
"General purpose compute architectures considered in the compute domain are ARM and x86. These two architectures are used as examples."
