It's up to them whether they want to limit it or not and this is a driver limitation not hardware so someone will unlock it for sure it's only a matter of time. at the end of the day miner will look at the price, availability and the hashrate it will produce, no one sell at MSRP here so have to wait until it hit the market and see the hashrate. If it's only hashing at 45 or even lower then i guess it's not worth it for miner, they will just buy 1660 super (cheaper), 5700 (more hashrate), or even 3060ti (efficiency at it's finest).
