I didn't see this option in the REST API document , but you can try the following:
You need to know the package id and artifact version id (in my case package id is 417 and artifact version is 3350)
The REST URL is http://RASERVER:8080/datamanagement/a/artifact_packages/417/artifact_versions/3350 (Method is PUT)
As always its better to create new idea for this request so it will be consider for future versions
