Are OpenZeppelin Accounts in Starknet Cairo upgradable contracts?

Hey, I wanted to know if the accounts deployed using hardhat OpenZeppelin in starknet cairo are upgradable contracts.

I am inquiring about this, since, After the starknet regenesis, if i am not mistaken, to migrate the already deployed contract to v1 of cairo, the existing contracts will need to be a upgradable contracts. So i just wanted to make sure that the accounts deployed using hardhat are upgradable as well, since the admin of the contract already deployed at the moment is the account deployed using hardhat OpenZeppelin.

Thanks.
