I've found something similar in Ducimus Tweak Pack for GWX:

-Compromised Realism cam. You can F12 free view around your sub, but can't use the Next/previous camera keys to sneak a peak at sonar, radar, and RWR contacts. Sort of a cheat really. This removes that temptation. Gameplay realism values have been changed accordingly.
Seems not exactly what you want but perhaps worth a try.
