As is, there are a few options, see the list below. I don't think it is possible to write arbitrary text in the CPU model name, at least not without modifying the KVM source code. It is common thing here, they will modify firmware of GPU from 10 years ago and sell as RTX 1080. Is it possible the seller has hacked CPU also?
