Oculus Integration SDK v40 still has broken shaders?

I just downloaded the Oculus Integration SDK version 40 and imported it into a new URP project.  The release notes say all shaders have been upgraded to work with URP, but I'm still seeing magenta when using the passthrough shaders found in Assets\Oculus\SampleFramework\Usage\Passthrough\Materials. 

SelectivePassthrough.shader is the one I'm particularly interested in, it's CG and I as far as I know URP requires HLSL.  Are the URP compatible shaders in a different location?
