Avoid double quotation marks in CSV file exported with PHP

It is possible to prevent the CSV file from coming with aspas duplas in string fields, I am using the script below, but the nome field is coming between aspas duplas , how can I avoid this?

<?php//export.phpif(isset($_POST["export"]))  
 {  
      $connect = mysqli_connect("localhost", "root", "", "simrede"); 
      if (mysqli_connect_errno())
      {
      echo "Falha ao fazer conexão: " . mysqli_connect_error();
      }

    // Set utf8
      mysqli_set_charset($connect,"utf8");
      $connect->set_charset('utf8');
      header('Content-Type: text/csv; charset=utf-8');  
      header('Content-Disposition: attachment; filename=Gabaritos_OMR_Alunos-Simrede.csv');  
      $output = fopen("php://output", "w");  
      fputcsv($output, array('ROLLNO', 'NAME', 'CLASS', 'EMAILID', 'PHONENO'),';');  
      $query = 'SELECT ROLLNO, nome, concat(".",nivel,"ano"), concat(id,"@gmail.com"), siem_id from cs_gabarito';  
      $result = mysqli_query($connect, $query);  
      while($row = mysqli_fetch_assoc($result))  
      {
           fputcsv($output, $row,";");  
      }  
      fclose($output);  
 }  
 ?>

  

Edit
  The answer from Júlio Neto using fwrite and implode served, it was enough to add line break in the last field of the query to avoid joining the last field with the   first of each line, as follows:

..., concat(siem_id,"\n") from cs_gabarito';
