idk but repurposing GPUs like that in the west will get you instantly in trouble with the law, most likely IP infringement since you are modifying Nvidia's stuff without approval for financial gains.

Chinese factories can do this without worries since Chinese law probably don't care about this all that much. And even if NVIDIA do hit them, they'll simply close down temporarily and rename themselves to a new entity altogether, it's common practice in China to simply "disappear" if something bad happens. That's also why you see so many chinese brands with incoherent letters and namings, because those names are disposable and not hard to come with.
