From where? Electrum or an exchange? If an exchange then there should be a way, just contact the support the team and they'll tell you what to do. If it's Electrum, then do you have the seedphrase?
I also think if the exchange is a KYC exchange and his account has gotten verified, the exchange will help him recovery the account. But if the exchange is a non-KYC exchange or he has not gotten verified, it is possible the exchange will not help him recover the coin. I have read about this very well in the past. Also wallet like bBockstream Green has 2FA wallet. It has both 2-of-2 and 2-of-3 2FA wallet. But it is still the same question which is the seed phrase needed to recover the coins if it is a noncustodial wallet.
