Is it possible to unlock all of the BF6 rewards through the BF2042 Free Pass as a new player?

I'm considering getting EA play for 1 month so i can get all of the unique cosmetics for BF6, Is it possible to do it or are there weapon/gadgets requirements you need to unlock first?

And how long does it take to unlock everything

And if my subscription runs out before BF6 release do i still get the rewards?

Thankyou.
