How to replace URP's default Light2D.shader with a custom version?

I want to write a custom version of URP’s Light2D.shader to create special behaviours.

I obviously don’t want to edit the shader file that is in the package. But I can’t find a place to replace or disable to the version in the Universal RP package.

How can I get my renderer to use a custom version of Light2D.shader instead of the default?

Thank you!
