Assuming you have the AWS SDK installed in your project using composer; specifically...

composer require aws/aws-sdk-php

Yes you can, using the stream wrapper like this:

require "vendor/autoload.php";

$aws_file = 's3://bucketname/foldername/your_file_name.pdf';

//the folder is optional if you have one within your bucket

try {

    $s3->registerStreamWrapper();
    $mpdf->Output($aws_file, \Mpdf\Output\Destination::FILE);
}
catch (S3Exception $e) {

    $data['error'] = $e->getMessage();
    //show the error as a JSON callback that you can use for troubleshooting
    echo json_encode($data);
    exit();
}

You might have to add write permissions to your web server as follows (using Apache server on Ubuntu AWS EC2):

sudo chown -R www-data /var/www/html/vendor/mpdf/mpdf/src/Config/tmp
sudo chmod -R 755 /var/www/html/vendor/mpdf/mpdf/src/Config/tmp

Then edit the ConfigVariables.php file found at:

\vendor\mpdf\mpdf\src\Config

Change:

'tempDir' => __DIR__ . '/../../tmp',

To:

'tempDir' => __DIR__ . '/tmp',

Then create an empty folder named 'tmp' in that same directory. Then upload with joy.

            'key'    => AWS_S3_KEY,
            'secret' => AWS_S3_SECRET,
        ]
    ]);

    $s3->registerStreamWrapper();

} catch (S3Exception $e) {
    die($e->getError().' => '.$e->getMessage();

To do this you could use the AWS SDK for PHP.

First you will need to create a client using your profile credentials.

use Aws\S3\S3Client;

$client = S3Client::factory(array(
        'credentials' => array(
            'key'    => 'YOUR_AWS_ACCESS_KEY_ID',
            'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
        )
    ));

And, if the bucket already exists, you can upload your file from the file system like this:

$result = $client->putObject(array(
    'Bucket'     => $bucket,
    'Key'        => $file_name,
    'SourceFile' => $pathToFile
));
