Total deactivation of Siri

Dear community

I want to deactivate Siri totally.

I went to the settings / Siri & Search and deactivated everything I could.

Just underneath this screen, apps are displayed.

If I click on one of these, I can deactivate Search & Siri Propositions.

I can also deactivate this option.

I would now have to do this for every app.

Is there a way to do it for all the apps at the same time?

...

Kind regards
