[2023] Alpha 2 as Christmas gift

Hello all, As Christmas is coming up and alpha 2 has been announced for 2024 I'd like to purchase an alpha 2 key and gift it to my little brother who I've always played MMOs with growing up. My question is if there is anyway to purchase this as a gift to send him while keeping it as a surprise? When I enter the shop now on my account I cannot buy an additional alpha 2 key since I got one last year. I'd rather not create a throw away email as I think he'd like to keep his email as the one used for the account and if I ask for access to his email then the surprise will be ruined. Is there any work around for this that anyone know of? Can you switch email for the account later on? I'm grateful for any advice. Merry Christmas and Happy New Year to you all!
