Requesting DirectX 9.0

Is there a way to tell Unity thru its GUI to use DirectX 9.0?

I’m seeing some issues with a shader from the Unity Asset Store, and it mentions d3d11:

So, I’m thinking switching to 9.0 may remedy some of these issues.

Thanks.

Use -force-d3d9. See:

Then, I ran Unity again. However, it still says the original message where it mentions d3d11.
