One way that companies get around ITAR and similar regulations for things like space grade components that have radiation tolerant features is to only rad test up to what the limits are. The components are probably much more resilient than what they are specced for but by only declaring the legal limit, companies can still export their products. The foreign buyers can do their own testing to prove the components can meet their required levels. I've done this before for a commercial chip that was rumored to be radiation tolerant despite nothing from the vendor saying so and found that it well exceeded my expectations.

I wonder if Nvidia can use a similar loophole where the chips are clocked at lower rates for export to meet the law but can be "overclocked" with hardware modifications.
