Can I create dumb "proxy" (vpn) record that will in fact act as "no proxy"?

[onetimecontributor]

I want to keep one of my real VPN proxies to catch all aps unless they're assigned to other proxy. It's done via "Always-on" in Advanced mode. That sounds like a safe way, so if I "loose" some app (or for new ones), it will not leak/access internet directly.
However, there are few apps that should have direct access to internet under certain circumstances.
I thought I could group those apps under "dumb" proxy record and enable/disable it on demand (lockdown = on), while still having default "Always-on" in another real vpn profile. So if I disable that dumb proxy, assigned apps are blocked, instead of (current) allowed (if to use "bypass" instead of requested "dumb" proxy).

Thus, is it possible to prepare vpn cfg file for import that will result in actual "no proxy" behavior?
Like set no keys, peer address to local, etc...
