I'm sure it can be modded .... by modders who choose to. I remember in Aces High and Air Warrior that the game programmers made the decision not to create skins on their end that depict anything related to the Nazi party due to the sensitivity in Germany, specifically (being internationally marketed games). I'm not sure if Ubisoft has the same policy but I wouldn't be surprised, being based in Europe. Such sensitivity also can be individually based. While I, personally, am not offended by historically accurate markings and flags (though I'm no German Wermacht or Nazi WWII historiphile [is that a word?] by any means) I can fully respect modders who opt out .... or not.
Just opining. Obviously this doesn't help with the request, specifically. Wish I could mod.
