[2022] Buy boxed version of Anno 1800 with already owning game possible?

Hi all!
Hope this forum is right for my question.
I want to buy the German boxed edition of Anno 1800 called "Königsedition". It contains a CD with the soundtrack, some artwork cards, the main game with a digital code and season pass 1 and 2.
But I already own Anno 1800 digitally with my Ubisoft account because I pre ordered it before the release. I am wondering if it is possible to activate the "Königsedition"-Code though and obtain the additional season pass contents or if this is "blocked" because I already own it.
Would be happy if anyone can help.
Thanks!
