BF6 Beta Rewards Transfer Between Accounts

Unsure where to post this, but I have 2 EA accounts: One linked to my Steam, and the other to my PC Game Pass. I wanted to unlink my Steam and link it to Game Pass to unify my library, but I realized that I may lose my rewards for participating in the beta, which I did via my Steam account. I reached max career rank and completed all challenges. I sent my issue to EA Help, but it was unclear how they would respond to me if at all. Is there any way I can redeem my rewards so long as I can prove I own both accounts?

Thanks.
