android - Change Blur Background color behind AlertDialog

Question

I want to change the black transparent background to white transparent, tried to change it in the AppTheme style but it didn't work.

Also I want to change the black blur background to white blur, tried to change it in the AppTheme style.

I also tried renderscript, fastblur, xml mentioned in this, but it changed only the dialog white background

Any ideas how to change it? Thanks in advance!

Using the style you can change the dim not the blur.
You can use the android:backgroundDimAmount attribute (range: 1.0 - 0.0):

<style name="ThemeOverlay.App.MaterialAlertDialog" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="android:backgroundDimAmount">0.xx</item>
</style>

and

MaterialAlertDialogBuilder(context, R.style.ThemeOverlay_App_MaterialAlertDialog)
    .setTitle("Title")
    .show()

With 0.10 and 0.90
