Career: change realism in the middle of a patrol?

[BarjackU977]

Hello,

Still trying to understand why my torps don't hit, or detonate on my small merchant target in rough sea (wind at 15 m/s), I would like to enable external view in the middle of a patrol.

I know I can't do that using the norlam interface, but I though that maybe by editing some files, it can be done.
However, I didn't find any information on how to do this, and failed to find files with settings that allow me to do so.
So, I doubt that there is a way, but can anyone confirm? Thanks!
