Can I roll back to an older URP package?

I am using Unity 2019.3.0f3 with Universal Render Pipeline 7.1.7. I am finding that Multipass stereo rendering renders left eye only and one forum post indicated that rolling back to URP version 7.1.5 fixed the issue. But the package manager window only offers back to 7.1.6. Is it possible to install 7.1.5 by any other means?

Thanks

Unfortunately, it is not possible to rollback to previous versions of URP via the package manager.
However, a possible solution would be to also rollback the Editor version by a couple of patches. Sometimes the compatibility between the C++ and C# code requires minimum versions to compile.
