Forbid certain changes on Android

I often face the following problem: an old person, absolutely not tech-savvy, is using an Android phone and is not contactable anymore because he/she has inadvertently muted its phone which doesn't ring anymore when one calls him/her, or has turned it off and doesn't know how to turn it on again. More generally, he/she has inadvertently changed any setting, the change leading to more difficult use of the phone for him/her. I would like to prevent that kind of issue by forbidding that kind of changes and ideally, natively. That is, without installing a new app -- because I saw apps allowing macro programming or even remote control, but I don't want processes running on that person's phone, nor do I want to control his/her phone on a regular basis to reinstate correct settings. (Except if there's no reliable native solution.) The phone in question is a Samsung Galaxy S10+ under Android 12. Is there something standard regarding this matter?
