Modern warfare ps4 uk / french version in german?

I bought the uk / french version of modern warfare on amazon. (didn't notice).

If I go in the settings I can only change the language between English and French. (ps4) My question now is whether I could somehow put it in German. No matter how.

thank you in advance

(sry for spelling, wrote quickly on the phone)

This is not possible

Actually you should be able to change the system language and thus the game language on the psy4 in the settings…
