how to activate real-view graphic for Nividia GTX 1660 TI ,windows10?

I copied out the name of the card under "Current", which is "GeForce GTX 1660 Ti/PCIe/SSE2". then created a new key in the NV40 and even tried in the "Other" folder per a user from another forum's suggestion and have tried all kinds of different "Value data" numbers. I believe the correct number for the 1070 Ti is 31408 because it has Pascal architecture and that's the same as cards such as the P6000, so I just used that number. No matter what variants of this I try I still can't get it to work.
