What kind of data do you want to add ? Any reason why it has to be this file in particular ? – Raphael at Digital Pianism Oct 7 at 10:10

\Magento\Framework\App\DeploymentConfig\Writer class is responsible for write deployment configuration. You can ask it in the constructor of your controller and then save data.

Example code:

<?php

class MyAction extends \Magento\Framework\App\Action\Action
{
    public function __construct(
        Context $context,
        \Magento\Framework\App\DeploymentConfig\Writer $deploymentConfig
    ) {
        parent::__construct($context);
        $this->deploymentConfig = $deploymentConfig;
    }

    public function execute()
    {
        echo $this->deploymentConfig->saveConfig([ConfigFilePool::APP_ENV => ['your_key' => $data]]);
        die();
    }
}

To use saveConfig() func we need to inject Magento\Framework\App\DeploymentConfig\Writer; – Rahul Oct 12 at 4:30
    
eg :-$this->writer->saveConfig([ConfigFilePool::APP_ENV => ['your_key' => $data]]); – Rahul Oct 12 at 4:32
