Cuda Toolkit 11.0 and Mathematica

I am on Windows 10, 1909, latest
I have RTX 2070
I installed CUDA Toolkit 11.0
I installed Visual Studio 2019
Everything upgraded to latest.
I grabbed NVIDIA repo of CUDA samples from github
I compiled 2 different cuda apps and they work fine, so installs all look good.
I have mathematica 12.1 (latest) but it cannot use CUDALink for some reason.

Help? Is it require to go back to CUDAToolkit 10.2? When can we use 11.0?
