Unity adds READ_EXTERNAL_STORAGE permission choosing split binary to obb

Hi I am using Unity 2017.2 and and my game takes more than 100MB so I spitted it to OBB files using the option “Split Application Binary” . The problem is that when I ever I choose this Unity adds READ_EXTERNAL_STORAGE permission and that open a permission popup in android when the game starts asks to grant permission to access my photos and other files in the storage.
This happens when I start an empty project with nothing in it and the default settings . If I build the APK for same empty project without the split option. The APK do not asks for any permission.
The minimum API version I chooses is 4.1 and the Target is automatic

BTW I have also tried it with 2017.3 Beta and the same thing happend

Is there is any way to solve this? So I will not need the permission when using the expansion files
