  return (
    interfaceId == type(IERC721).interfaceId ||
    interfaceId == type(ERC2981Collection).interfaceId  ||
    interfaceId == type(BAYC).interfaceId  ||
    interfaceId == type(ContractURI).interfaceId  ||
    interfaceId == type(IMAX721).interfaceId  ||
    interfaceId == type(IMAX721Whitelist).interfaceId ||
    interfaceId == type(ReentrancyGuard).interfaceId ||
