Scheduled disabling of android apps that cannot be disabled during the active period

I’m currently using FocusMe to accomplish this task. The issue is that I can just uninstall the app during the active period to get access to my previously disabled apps. I need a solution that will make it impossible (or just really time consuming) to disable a scheduled disabling of apps on my android phone. I haven’t found an app that can do all of this and i haven’t found an "app lock" app that will completely prevent me from uninstalling FocusMe (or whatever other app) and the "app lock" app. If I have to I can root.
