Easy Mobile - Many-in-one package for mobile games

Hi, I am facing this problem. Unity 2019.x IL2CPP crash on Android 8
I want to edit AndroidManifest.xml under “/Plugins/Android/CoogleMobileAdsPlugin”. and I Did it easily.
But … I can not edit the AndroidManifest.xml under “/Plugins/Android/EasyMobile”

How can I add this to the application tag:
"android:allowBackup=“false” tools:replace=“android:allowBackup”
Thanks
