Kotlin Navigation Component 控制何时显示hamburger或后退图标

我有以下活动

class MainActivity : AppCompatActivity() {

private lateinit var drawerLayout: androidx.drawerlayout.widget.DrawerLayout

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.main_activity)

    drawerLayout = drawer_layout

    val navController = Navigation.findNavController(this, R.id.fragment_main_navHost)

    setSupportActionBar(toolbar)

    NavigationUI.setupActionBarWithNavController(this, navController, drawerLayout)
    navView_main.setupWithNavController(navController)
}

override fun onSupportNavigateUp(): Boolean {
    return NavigationUI.navigateUp(drawerLayout,
        Navigation.findNavController(this, R.id.fragment_main_navHost))
}

override fun onBackPressed() {
    if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
        drawerLayout.closeDrawer(GravityCompat.START)
    } else {
        super.onBackPressed()
    }
}

正如你们所看到的，它与导航图有关，我使用的是一个导航抽屉.当我浏览抽屉中的物品时，我想保留汉堡包图标，仅当我点击片段或弹出窗口中的物品时，才将其更改为向上/后退按钮，并确保系统的行为根据显示的图标反映用户的期望.有可能吗
