Not that I’m aware of. Hardened mode checks software/programs against a whitelist before the app will be allowed to run.
If you are speaking about “deepscreen” just download and run autosandboxme2. 
Not to worry, if you run Hardened Mode on aggressive it’s just a matter of time and you’ll be alerted.
I use the moderate setting and have found in daily internet use, is fairly chatty.
