Allow overriding of lambda@edge origin-request for custom paths

Is your feature request related to a problem? Please describe. I have a custom path on my NextJS app that I want to route through a custom Lambda@Edge function of my own, but this code overrides it even if I provide it in the input configuration.

Describe the solution you'd like Allow the override to happen, I don't think it makes sense to have a configuration that gets overridden always.

Describe alternatives you've considered Since I can't do this override I have to manually edit the default-lambda code using a custom script on the build.postBuildCommands.
