Is Hero 12 black good for Subzero Summer Antarctica temperatures?

Online reviews say -10 degrees centigrade is supported unofficially, but is it till -20 workable? There are cases where I'll be in the helicoper which means more wind hence will get cool faster. I may face a bit of snow storm too. I'll be buying enduro batteries, will they be good enough? I saw that DJI action 4 supports -20 degrees centigrade but it's bad in other way which matter for me, namely HDR and MP. Should I still go for it. It'll be mostly day for me as I'm going in summer.
