Disable screen time but keep in-app purchase restriction

Hi all, I find that with the 12.3 update, my screen time is draining my battery very quickly. This is especially obvious overnight where it can drain up to 50% on some nights. I want to disable screen time but it contains the in-app purchase restriction. I'm not sure why the content and privacy settings were moved under screen time but this just seems to be a bad idea. How do I keep the in-app purchase as "not allowed" while disabling screen time?
