You can dynamically inject static value to a dynamic SQL call as in:

SET @minEmptyId := 1337;
CALL statement(CONCAT('
  ALTER TABLE tableName
  AUTO_INCREMENT = ', @minEmptyId))
;

statement procedure implementation:

DELIMITER $$
CREATE PROCEDURE statement(IN dynamic_statement TEXT)
BEGIN
      SET @dynamic_statement := dynamic_statement;
      PREPARE prepared_statement FROM @dynamic_statement;
      EXECUTE prepared_statement;
      DEALLOCATE PREPARE prepared_statement;
  END$$
DELIMITER ;
