Possible to remove a co-owner from registration of Model Y

[apseattle]

I"ve a friend who has a model y reservation and he doesn't want it and I'm ready to buy the reservation and he added me as a co-owner to the registration. Is there a way to get around me buying it and taking loan as a signle sign on rather than a so-signer. Has some one gotten the delivery done in this secnario?

I'm located in Seattle and he's located in bay Area and he's able to make the address changes as well.

Appreciate your response.
