React tab bar navigator keeps displaying a shadow bar. I do not want a border or a shadow above the tab navigator

In my emulator this happens

Expected behaviour

I have tried

style: {
            elevation: 0, // remove shadow on Android
            shadowOpacity: 0, // remove shadow on iOS
            shadowOffset: {
                width: 0, height: 0 // for iOS
            },
        },
        indicatorStyle: {
            width: 0, height: 0, elevation: 0,      
        }

and

style: {
            borderTopWidth: 0,
            elevation: 0
          }

and

<Tabs tabContainerStyle={{ elevation:0}}></Tabs>

and ShadowVisible: false, and a bunch of other things
