Disable all unneeded apps when working in remote wildland areas?

I'd like to disable all apps I don't need when I work in remote wildland locations. It's too easy to activate unneeded apps to find out after-the-fact that my battery has been drained while the unneeded apps search the skies for connectivity.

Maybe an example would help: I only need a mapping app, the files app (to access work reference docs), and the camera. I don't need or want to inadvertently activate safari, Apple Maps, or other web page badges etc saved on the home screen.

Maybe move all unneeded apps into one multi-page badge, leaving only the ones I need out on the home screen? That would be klunky and cumbersome. Things frequently get inadvertently activated due to the touch screen. Maybe an assistive touch fix? Is there a way to disable/enable the touch screen with assistive touch?

Thanks for any suggestions or solutions.
