Any way to explicitly specify images to use for components?

Any way to explicitly specify images to use for components? the custom registry option is formatting the images in a way that doesn't work for our mirroring, its only the http://k8s.gcr.io|k8s.gcr.io images really that are a problem as it formats them like ```<custom-registry>/k8s.gcr.io/sig-storage/csi-node-driver-registrar:v2.3.0``` instead of ```<custom-registry>/sig-storage/csi-node-driver-registrar:v2.3.0``` which is what our registry is expecting
