Override navigationCard styles

[NewOldMax]

Hi!
Thanks for this awesome library!

I have image on background in my app.

const style = {
    image: {
        flex: 1,
        width: null,
        height: null,
        resizeMode: 'cover',
    },
}

const Root = (props) => (
    <Image source={require('../assets/img/background.jpg')} style={style.image}>
        {props.children}
    </Image>
);

So, if I'm try to using <TabsRoute path="/" component={Root} transition="horizontal-pager">, then i have gray background instead image. I found in styles.js

navigationCard: {
    ...absoluteFillObject,
    overflow: 'hidden',
  },

Making this

navigationCard: {
    ...absoluteFillObject,
    backgroundColor: 'transparent',
    overflow: 'hidden',
  },

solve my issue.

Is there a way to override those styles?
