No, of course not. You can avoid using centralized exchanges altogether. If you wish not to disclose any of your personal information then do not use centralized exchanges unless you intend to just limit your transactions in the specified amounts which the exchanges are allowing for non-KYC users. If you are selling a lot of Bitcoins, better use P2P than decentralized exchanges. DEXs have lower volume. It might take time for your orders to get fully filled.
