Way to have CI_REGISTRY_IMAGE always point to origin, not fork?

CI_REGISTRY_IMAGE is the registry address where pipeline runs, so when run on a fork, it’ll be that of fork, not the origin. Is there a systematic way to always point to origin?

My usecase for this variable is to construct a image location in order to pull a registered image but a lot of times the image is only registered on the origin repo and not on the fork.
