I figure out the issue and the solution so posting the solution it may will help someone for drawable i reduce margin :

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
 <item>
 <shape android:shape="oval">
    <solid android:color="#785125"/>
  </shape>
  </item>
  <item
    android:drawable="@drawable/ic_action_settings"
    android:bottom="5dp"
    android:left="5dp"
    android:right="5dp"
    android:top="5dp"/>
  </layer-list> 

and in java code making icon tint as null works

  navigationView.setItemIconTintList(null);
