Magically Changing Settings: Remote Status Not Showing?!

I have noticed that both on my Mac Studio and on my Iphone settings change on their own as if someone is changing them remotely.

I have noticed that there aren’t ever messages prompting me to make these changes or notifying me of these changes; yet, I often have to go into the system settings and turn off Airdrop, blutooth, remote access and wifi auto connects whenever it wants, even when I have auto connect turned off. I feel these settings make it easier for someone to glitch and steal data I keep my data and wifi OFF until I am ready to use it and find these things have been tripped on MAGICALLY.

Additionally my Iphone; every model I have owned magically cut itself on.

Is there a feature or way to monitor these system changes?

Does apple have a way that the system will flag the user of ANY and ALL system changes?

Can apple find away for our devices to scan for a double or even jail broken phones?

Apple needs a feature that allows valid user to detect other administrative devices nearby?

Better yet how can we make our Mac undetectable?
