That's just one of the many annoying aspects of ai behaviour. I suppose a decrease in their overall persistence would be good so that they would just blooming go home sometimes rather than fighting on to the bitter end. That includes friendlies too.

Is it poss?

the best way to limit AI activity and get them to break off and go home is to limit their fuel...especially for BoB style missions where the 109's had only ten minutes over england...and they lost more splashing in the channel or crashing on the beaches of france than from combat
