Scheduler Settings has one panel: turning the module off. There is nothing else to configure here — everything about a task lives on the task itself.
Tasks → Settings.
What you can do here
The Disable scheduler module panel warns: "You can disable the scheduler module. All scheduled tasks will stop firing and related data will be deleted." Pressing the red disable button turns the module off and redirects you to the module home (/tasks), where you can enable it again later — but the tasks themselves are gone; you would create them again from scratch.
If you only want to pause one task, do not disable the module — use Disable on the task itself in the Tasks list.
