No.. it happens if you enable iCloud at all, not just iCloud Drive. There is no "enable documents in the cloud" setting. According to Apple's KB, just signing into iCloud makes iCloud the default location for all unsaved docs (for iCloud-enabled apps).[1] So even if you've just turned on iCloud for photo streams or syncing contacts or whatever, iCloud becomes the default location for all unsaved docs.
