Hello Siddharth Joshi,
Currently, Purview doesn't support connecting to a DevOps Repo to promote code changes from one environment to another.
However, here is a document that identifies common tasks that can help deploy Azure Purview into higher environments: Azure Purview deployment best practices and deployment models
You can follow this document to deploy artifacts from one environment to another. This involves exporting the Purview artifacts from the source environment, storing them in a version control system, and then deploying them to the target environment using the Purview REST API.
