There is no way that would have been possible. And as I saw another commenter mention, even if NVidia were founded much more recently when dual share structures became much more common, you rarely (or maybe never, I can't think of any cases) see that dual share structure in very capital intensive industries like hardware where you have to sink a ton of money into the enterprise before you even see any revenue. Software is a whole different ball game.
But Elon Musk has supermajority through dual-class shares in SpaceX which is obviously a capital-intensive business even more so than making GPUs.
