Per-page article comment disabling is not available on the legacy platform but it was recently made available on UCP. When you edit the page, the bottom editor bar should have a checkbox for enabling/disabling comments. Note that some users have had a buggy experience with this feature. It may take a few tries before the setting is properly changed.
