How do I turn off automatic updates from Apple ?

Is there any way to turn off the automatic updates so you don’t have to install them on your phone? It seems like every new Apple update changes the way your phone works, and I already like the way my phone works. I don’t wanna change it. The new 18.1 update already says it will change your phone, your pictures and the way you view them. I already liked the way I see them and I don’t want them to change so I don’t want the update. Is there any way to stop them from automatically updating my phone or asking me to update all the time?
