要在Android Jetpack导航组件中禁用滚动位置，可以使用FragmentNavigator类的onCreateDestination方法。以下是一个示例代码：

class DisableScrollFragmentNavigator(
    context: Context,
    manager: FragmentManager,
    containerId: Int
) : FragmentNavigator(context, manager, containerId) {

    override fun onCreateDestination(): NavDestination? {
        val destination = super.onCreateDestination()
        destination?.let {
            it.addDeepLink(it.id.toString())
        }
        return destination
    }
}

然后，在导航图中使用此自定义FragmentNavigator类。示例如下：

然后，在Activity中设置自定义的FragmentNavigator类：

class MainActivity : AppCompatActivity() {

    lateinit var navController: NavController

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

        val navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host_fragment) as NavHostFragment
        navController = navHostFragment.navController

        val disableScrollNavigator = DisableScrollFragmentNavigator(this, navHostFragment.childFragmentManager, R.id.nav_host_fragment)
        navController.navigatorProvider.addNavigator(disableScrollNavigator)

        val navGraph = navController.navInflater.inflate(R.navigation.nav_graph)
        navController.graph = navGraph

        // ...

    }
}

这样就可以在Android Jetpack导航组件中禁用滚动位置了。
