Is it possible to change "New WordPress Site" notification that is received after WordPress site creation in Plesk?

Question

The following notification is received after WordPress site creation in Plesk:

CONFIG_TEXT: From: "WordPress" <wordpress@example.com> 
Date: Aug 21, 2017 1:34 AM 
Subject: New WordPress Site 
To: <admin@example.com> 
Your new WordPress site has been successfully set up at: 
https://example.com 
You can log in to the administrator account with the following information: 
Username: user 
Password: The password you chose during the install. 
Log in here: https://example.com/wp-login.php 
We hope you enjoy your new site. Thanks!

Is it possible to change it's content?

Answer

The notifications are sent via  wp_new_blog_notification function, which is a built-in WordPress function.

This is an official description of the function:

Sends an email with wp_mail to the new administrator that the site setup is complete, and provides them with a record of their login credentials.

It is not possible to change it by creating a predefined template for WordPress since each time a new WordPress site is created, the templates are downloaded from wordpress.org and then deployed.
