If you really, really want to manage PII in a private git repo, you can probably do it - in approximately the same that you can probably make API-first web services in FORTRAN if you really, really want to. The fact remains that your choice of tooling hurts you. Putting PII into Github (even if the repo is private) is catastrophic. You just made Github into a third-party data processor by accident. Good luck explaining that from a CCPA/GDPR perspective.
