Google Drive showing device data without my consent

I signed in three Google accounts in my android phone.

In Google account synchronization settings, I un-checked Google Drive so that no data from Google Drive server synced to phone and no data from phone should be saved on Google Drive server.

However, when I open Google Drive, I see phone data in Google Drive. As I said, three Google accounts are signed in android phone. It is picking any account’s Google Drive randomly.

I uninstalled Google Drive and re-installed it.

However, I see same issue.
