Remove nofollow

My client has content behind a paywall and it appears that woocommerce subscription places a nofollow tag on these posts.

However after a period of time he would like to open these posts up and make them available for indexing.

When he removes the paywall on these posts the nofollow tag remains so they aren’t indexed.

Is there a configuration setting that removes the nofollow for posts that are no longer behind the paywall.
