Vercel: Private Past Production Deployments

Hope you liked all of the alliteration in the title. Anyways, I was wondering if there is a way to prevent previous versions of production deployments from being publicly accessible. I'm aware that this is possible for preview deployments, but I wasn't able to find a way to do this for production deployments. I see that there is an option to "Also protect my Production Deployment" (see screenshot), but the wording implies that this is for all production deployments, rather than just previous ones (even if it did, I just have the hobby plan for now). Thanks for your help : )
