How to change Default FBX Animations import options

I just want to uncheck the "Import Animation" Check-box by default when I import a FBX.

I tried to use this script, it works for the "Rig" tab, but not work for "Animations" tab

thanks

 using UnityEngine;

 using UnityEditor;

 using System;

 public class CustomImportSettings : AssetPostprocessor 

 {
 void OnPreprocessModel() 

 {

     ModelImporter importer = assetImporter as ModelImporter;

     importer.swapUVChannels = false;
     
     importer.generateSecondaryUV = true;
     
     //this line is not working
     importer.generateAnimations = ModelImporterGenerateAnimations.None;
     
     importer.animationType = ModelImporterAnimationType.None;
     
 }

}
