Intel has this too. If this is the feature I think it is.

It's available on a "per-CPU-lot" basis.

If Tyan were to build 10,000 systems, it would say to Intel
"Hey, Intel, I need a Tyan-only signature stamped on this CPU".

Actually if you watch the video link that I provided, this is not the
exact same feature. This feature may come to Intel with the next
generation of Xeon processors.

It sounds like right now Intel has to special manufacture some
processors at the factory that stay locked to a specific vendor. Whereas
with this AMD feature, no special processors need to be manufactured,
it's all available with a standard Epyc processor. The Epyc processor
modifies its locking status after initial boot. The potential exists
that you can even get per-customer locking with this, where a special
crypto key is made for a large customer and all of the processors are
locked to that customer forever.
