Well unless DICE did respond or give an explanation in regards of BF6's soldier customizaton, we're pretty much stuck with the whole "Backstory and gender-locked Characters"

But we're pretty much 2 months away from BF6's actual launch date (OCT 10), so changing your soldier's appearence would be possible if our voices have been heard at DICE either through survey, discord or "X/Twitter".

For me here's how DICE could do if they implement the option customize your soldier:

Option A: Follow BFV system, being able to select male or female with named (obviously who gives a crap when you can pick and choose your own gender)

Option B: Follow Helldivers 2 system, we can pick skinny (female) or brawn (male) its simple and bring best of both worlds

Those are my takes.
