NormalMap support?

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.1/manual/renderer-feature-decal.html

Unity 2021 introduce it's Decal system in URP Ver.12. I found it's Screen Space technique is similar to this solution.

Is it possible to implement NormalMap feature into this repo here so that lower URP version like Ver10 can have a Normal support decal?
