What good are rerolls if I can't reroll Bonus Challenges

I've been working towards unlocking this weeks bonus challenge in the hopes I could reroll it (currently it is do 15 missions in RedSec), only to find out that you cannot reroll bonus challenges. To be clear I am interested in RedSec, the problem is none of my friends play BF and I really do not want to deal with squadding up with randos while I'm trying to do 15 missions. As such, I feel like even though I bought the base game at full price, I'm being punished for not fitting the conditions BF Studios seems to be forcing on people to play RedSec. I mean I don't even get the point of adding rerolls if bonus challenges can't be rerolled given normal weekly challenges will be available for the full duration of the battle pass. Only the bonus challenges are time sensitive which would make rerolls extra useful given they're not only time limited but you have to unlock them to begin with.

If I'm going to be forced to play RedSec every week in a way that would likely annoy the random people I have to squad up with, I don't know why I would bother buying the Battle Pass as I feel like I'd be at an unfair disadvantage for something that's basically out of my control.
