11xx series will mostly be disabled for mining at the driver/bios level. Like you cant SLI more than 2 cards in 10xx series, similarly the cards in 11xx wont work for compute loads if more than 2 are installed in the system.
Thats the best solution NVidia will have to isolate itself from last times crypto disaster.
Why would NVIDIA limit GPUs from mining/compute loads when they made a big profit of miners just recently? A potential move from them would be to cater to both gamers and miners by having seperate GPUs for graphics and for compute loads.
Banning a certain type of consumer makes no sense. Given that while miners RMA more, i'm pretty sure they also buy more GPUs which balance everything out.
GPUs are on their last legs, by December FPGAs will have swamped them. And parallel to that ASICs will take whatever is left, look at Equihash, many coins dont seem to care about ASICs. And soon ETH will be similar story. NVidia will not need mining customers as there wont be many.
Compute loads (apart from mining) can be served by a separate line of appropriately higher priced series of cards with no graphic functions.
