Prepared Report Auto-Enable even after switching to Disabled

This looks like an open issue already based on some posting

But it seems like when a report is switched to disabled prepared report it will still be automatically set to enable prepared report after a given time. Below is the snapshot of the code from the Report Doctype that is causing this

This means that no matter if you disable the prepared report it will still be switched behind you and will still cause the same issues as why you disabled it in the first place.
