Bridgecrew Action - Docker Pull Rate Limit

[chadatprimer]

We are seeing

Error response from daemon: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: docker.com/increase-rate-limit
  Warning: Docker pull failed with exit code 1, back off 3.146 seconds before retry.

How do we set the Action to only pull from an internal repo?

We've had to fully pull Bridgecrew from our actions until then.
