How replace setSupportActionBar by styles?

Question

In my android app, I can't use AppCompatActivity. I have no source code of this part of the project. So I use

androidx.fragment.app.FragmentActivity

app theme:

<style name="MainAppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">

my layout with toolbar:

<androidx.drawerlayout.widget.DrawerLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">


    <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

        <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolBar"
                android:layout_width="match_parent"
                android:layout_height="@dimen/tool_bar_height"/>
        <!-- Framelayout to display Fragments -->
        <FrameLayout
                android:id="@+id/frame_container"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
        </FrameLayout>
    </LinearLayout>    

</androidx.drawerlayout.widget.DrawerLayout>

Here is my code snippet:

import androidx.appcompat.app.ActionBarDrawerToggle;
import androidx.appcompat.widget.Toolbar;
public class MainNavigationDrawerFragmentActivity extends androidx.fragment.app.FragmentActivity

mToolbar = (Toolbar) findViewById(R.id.toolBar);
toolbaTitleTextView = (TextView) findViewById(R.id.toolbaTitleTextView);
actionBarDrawerToggle = new ActionBarDrawerToggle(
    this,
    mDrawerLayout,
    mToolbar, 
    R.string.application_name,
    R.string.application_name) {
        public void onDrawerClosed(View view) {
            toolbaTitleTextView.setText(mTitle);
            invalidateOptionsMenu();
        }

as result toolbar is show but menu not show. To show the menu I need to use

setSupportActionBar(toolbar);

but I can't use this method, because I can't use AppCompatActivity.

Is it possible to replace setSupportActionBar(toolbar); by another method or maybe settings/styles to show menu it toolbar?
