Show/Hide Toggle for a Toggle

We have a toggle available in our main screen, to enable/disable an important functionality. Since, only 30% of our users use this functionality at least once per month, we are considering to (optionally) move the functionality toggle from the main screen to the settings, to make it less intrusive and less prominent to our 70% of our users.

We believe it should be optional, so that we allow the 30% of our users to keep it available in the main screen.

Our problem is the following:

User can enable/disable the functionality either from within the main screen or from the settings, however, he is allowed to show/hide the toggle from the main screen, if he finds it less useful.

Technically, we want to introduce a "show/hide" toggle, for a toggle...

How can we communicate this, without impacting the cognitive load of our users?
