Insular, a FLOSS fork of Island, allows you to isolate privacy invading Android apps and prevent them from running when you don't want them too.

I use this with grapheneOS and it provides a great amount of customizability that I want. I've had no problems with the app at all the the past year I've been using it. I keep all the apps that require Google to function locked away and only use them when I absolutely need them. I no longer worry about apps constantly doing god knows what with my data while I go about my daily life.
