How to change TIMEOUT for Drush command

I am working on a website with an extremely heavy database.

As a result, the command drush sql-cli < [db_filename] takes more than default value of 14400 seconds.

I need to find a way how to change this value properly.

I found put that the function I need is setTimeout() from the vendor/symfony/process/Process.php.
I can use it directly in vendor/drush/drush/src/Commands/sql/SqlCommands.php like this:

public function cli(InputInterface $input, $options = ['extra' => self::REQ])
    {
        $sql = SqlBase::create($options);
        $process = $this->processManager()->shell($sql->connect(), null, $sql->getEnv());

        // Set timeout here.
        $process->setTimeout(36000);

        if (!Tty::isTtySupported()) {
            $process->setInput($this->stdin()->getStream());
        } else {
            $process->setTty($this->getConfig()->get('ssh.tty', $input->isInteractive()));
        }
        $process->mustRun($process->showRealtime());
    }

However, I do not want to touch the vendor folder, I think that the better solution is to write a hook or to alter an existing functionality any other way in Drupal module.
But I cannot understand how it can be done.

Could you please give me an advice on how to do this?

Edit
I know that I can create a patch and include it in composer.json of the project.
However, I would like to know if a better way exists.
