Is it possible to load particular screen in react native without navigation

You should use a state for represent home or profile. for ex:

    function HomeScreen() {
     const [screenName, setScreenName] = useState('home')
     if (screenName == 'profile') {
      return <ProfileScreen/>
     }
     return {
...
      // handling the event to go Profile screen
      setScreenName('profile')
...
     }
    }
