Unity ADS Package 4.1. and above should not add permissions automatically ; how to turn it off?

Hi,
Unity ADS Package 4.1 and above is adding the android permission com.google.android.gms.permission.AD_ID
automatically (see Installing the Unity Ads SDK for Android).
How to turn it off. I need to turn it off becaue the full commericial build of the unity android app need to be payed in the store and does not show ads.
( Only the free demo build of the same unity projects covers ads ).
Please help me. Thank you
