How can I customize the addToBackStack behavior, when not using navigation, but using supportFragmentManager.beginTransaction()

MainAcitvity.kt

package com.example.fragment

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import androidx.databinding.DataBindingUtil
import androidx.fragment.app.Fragment
import com.example.fragment.databinding.ActivityMainBinding

enum class FragmentName {
    HOME, PROFILE, ABOUT
}

class MainActivity : AppCompatActivity() {
    private lateinit var binding: ActivityMainBinding
    private lateinit var currentFragment: FragmentName


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = DataBindingUtil.setContentView(this, R.layout.activity_main)
        binding.root

        val homeFragment = HomeFragment()
        val profileFragment = ProfileFragment()
        val aboutFragment = AboutFragment()

        currentFragment = FragmentName.HOME
        changeFragment(homeFragment, false)

        binding.home.setOnClickListener {
            if (currentFragment != FragmentName.HOME) changeFragment(homeFragment)
            currentFragment = FragmentName.HOME
        }
        
        binding.profile.setOnClickListener {
            var addToBackStack = currentFragment != FragmentName.PROFILE
            if (currentFragment != FragmentName.PROFILE) changeFragment(profileFragment)
            currentFragment = FragmentName.PROFILE

        }
        binding.about.setOnClickListener {
            var addToBackStack = currentFragment != FragmentName.ABOUT
            if (currentFragment != FragmentName.ABOUT) changeFragment(aboutFragment)
            currentFragment = FragmentName.ABOUT

        }

    }

    private fun changeFragment(fragment: Fragment, addToBackStack: Boolean = true) {

        supportFragmentManager.beginTransaction().apply {
            replace(R.id.flFragment, fragment)
            if (addToBackStack) {
                addToBackStack(null)
            }
            commit()
        }
    }
}
