Helm chart repository - overwrite existing chart



I've deployed goharbor in the kubernetes cluster.
I've created a project with a helm chart repository, and I've noticed, I can push the same helm chart many times.
Is there a setting to configure, if I can overwrite existing chart in the given project? 
It's OK for the test, but for the production, I'd like to block helm chart overwriting.

Best regards,
Lukasz Lech
