As you can see below, I've tried many ways of setting the background color to transparent like this (UI required), all to no avail. The background remains grey-ish like the image

  <Tab.Navigator screenOptions={{
    tabBarShowLabel: false,
    swipeEnabled: false,
    tabBarShowIcon: true,
    tabBarItemStyle: { width: iconwidth },
    tabBarStyle: { backgroundColor: 'transparent', paddingBottom: 10},
    tabBarContentContainerStyle: {backgroundColor : 'transparent', display: 'flex', justifyContent: 'center', alignItems: 'center'},
    tabBarPressColor: '#3C60AA',
    tabBarIndicatorStyle: {width: iconwidth , height: 5, backgroundColor: '#3C60AA', borderRadius: 20, marginStart: iconwidth *0.61},
    lazy: true,
    lazyPlaceholder: () => <POTab_lazy/>
  }}>

    <Tab.Screen name="POTab_1" ponent={POTab_1} options={{ tabBarAccessibilityLabel: 'Info',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_info.png')} style={{width: 30, height: 30 }}/>), }}/>
    <Tab.Screen name="POTab_2" ponent={POTab_2} options={{tabBarAccessibilityLabel: 'File',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_file.png')} style={{width: 30, height: 30 }}/>),}}/>
    <Tab.Screen name="POTab_3" ponent={POTab_3} options={{tabBarAccessibilityLabel: 'Attach',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_attach.png')} style={{width: 30, height: 30 }}/>),}}/>
    <Tab.Screen name="POTab_4" ponent={POTab_4} options={{tabBarAccessibilityLabel: 'Link',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_link.png')} style={{width: 30, height: 30 }}/>),}}/>
    <Tab.Screen name="POTab_5" ponent={POTab_5} options={{tabBarAccessibilityLabel: 'Timer',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_timer.png')} style={{width: 30, height: 30 }}/>),}}/>
  </Tab.Navigator>

); }

POTab_1.js code looks like this

<ScrollView showsVerticalScrollIndicator={false}>
  <View style={{ flex: 1, justifyContent: 'flex-start', alignItems: 'flex-start', padding: 20 }}>
    
    <View style={{marginBottom: 15}}>

If you're trying to change the screens, not the tab bar itself, I found setting sceneContainerStyle to be the way to do it:

<Tab.Navigator sceneContainerStyle={{backgroundColor: 'transparent'}} >

If you want to set background color for the whole tab bar, then we need to provide the style in tabBarOptions prop to the Tab.Navigator.

Consider the following code snippet.

<Tab.Navigator
  tabBarOptions={{
    style: {
      backgroundColor: 'transparent',
    }
  }}>

Updated your code to include tabBarOptions

<Tab.Navigator screenOptions={{
    tabBarShowLabel: false,
    swipeEnabled: false,
    tabBarShowIcon: true,
    tabBarItemStyle: { width: iconwidth },
    tabBarStyle: { backgroundColor: 'transparent', paddingBottom: 10},
    tabBarContentContainerStyle: {backgroundColor : 'transparent', display: 'flex', justifyContent: 'center', alignItems: 'center'},
    tabBarPressColor: '#3C60AA',
    tabBarIndicatorStyle: {width: iconwidth , height: 5, backgroundColor: '#3C60AA', borderRadius: 20, marginStart: iconwidth *0.61},
    lazy: true,
    lazyPlaceholder: () => <POTab_lazy/>
  }}
  tabBarOptions={{
    style: {
      backgroundColor: 'transparent',
    }
  }}>

    <Tab.Screen name="POTab_1" ponent={POTab_1} options={{ tabBarAccessibilityLabel: 'Info',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_info.png')} style={{width: 30, height: 30 }}/>), }}/>
    <Tab.Screen name="POTab_2" ponent={POTab_2} options={{tabBarAccessibilityLabel: 'File',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_file.png')} style={{width: 30, height: 30 }}/>),}}/>
    <Tab.Screen name="POTab_3" ponent={POTab_3} options={{tabBarAccessibilityLabel: 'Attach',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_attach.png')} style={{width: 30, height: 30 }}/>),}}/>
    <Tab.Screen name="POTab_4" ponent={POTab_4} options={{tabBarAccessibilityLabel: 'Link',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_link.png')} style={{width: 30, height: 30 }}/>),}}/>
    <Tab.Screen name="POTab_5" ponent={POTab_5} options={{tabBarAccessibilityLabel: 'Timer',tabBarIcon: ({ tintColor }) => ( <Image source={require('../../assets/icon_timer.png')} style={{width: 30, height: 30 }}/>),}}/>
  </Tab.Navigator>
