The RTX 3060 hasn't released yet, so if the cards ship with this limitation, there aren't any old drivers to use.

I don't speak Russian but this video suggests otherwise: https://youtu.be/282Ozbp-Uv8?t=262

You're right, I forgot they package up drivers for all cards in the same versioning scheme, so using 4XX version of the package won't support the card.
