Internal file server / git references for Helm values schema (w/ versioning support)

[OneCricketeer]

I'm looking for an alternative to local filepath references, as while I can clone the Helm Charts with a values.schema.json file, that path is typically pointed at a main branch (or would be upon latest pull).

Is there a way to combine a local file path within a git repo with a tag checked out only for the reference? Maybe with some sort of caching mechanism so it is not modifying the actual cloned repo directory.

Alternatively, what are people using to host their schema-stores for internal usage that can provide some version query-param, e.g. $schema: http://artifact-repo/helm/charts/backend-app/values.schema.json?version=v1.0.1
