Nope. I go to Settings>>apps>>all apps>>Google+>>disable.By disable, do you mean you go to your apps & stop it? G+ will run in the background from time to time. You can go to Accounts & Sync, select your account & un-sync G+. That should cut down the times it runs in the background.
When I disable G+, play store no longer wants to update. A day later and it wants to update and the app is now enabled in settings.Its going to keep doing that as long as it's installed. Un-syncing can cut down the resources it uses. But until you update it, it's going to keep prompting you to do so. Unless you uninstall it
