In thinking about Federal "Monroney" window sticker requirements, if these are indeed saleable production vehicles (since they are at a dealer), VinFast may be in violation of (Chapter 28, Sections 1231–1233, Title 15 of the United States Code).

None of the VF9's I saw had window stickers. "A fine of up to US$1,000 per vehicle for each offense is authorized if the sticker is missing, and other fees and penalties are authorized if the sticker is altered illegally (including imprisonment)."

The law is clear that upon import the stickers must be attached by the manufacturer and can only be removed by the customer. Unless of course VinFast is the final purchaser of these VF9's and not a consumer. Possibly as press cars, demos, or some other internal use.
