com.android.providers.settings does not exists I am using Lineage OS 14.1-20171111_14ß556-UNOFFICIAL-cedric on my Motorola G5
Android 7.1.2 and i am not able to locate the file/data/data/com.android.providers.settings/databases/settings‌​.db

i tried ES File Explorer(with root) , adb shell (with root) and also SQLite Editor from the Play Store does not seem to find that file.
Since Marshmallow, all the settings are scattered everywhere, you won't find settings.db

many settings are available under /data/system/users/0/ saved as XMLs. Try looking there.
