It seems like your function is already set up to use Artifact Registry. Artifact Registry is the recommended service for storing and managing Docker images in Google Cloud, so your function should not be affected by the shutdown of GCR.
Here are the verification method:
Check your function’s configuration: Ensure that any other configurations point to Artifact Registry (e.g., in Cloud Build or CI/CD pipelines).
Documentation: You can follow the official Google Cloud documentation on Artifact Registry to ensure everything is set up properly and to explore migration details if needed.
