How to add additional Apache directives globally on a Plesk server?

How to add additional Apache directives by service plan or globally, so that these directives will not be overwritten by an update?

The following steps apply to each Service Plan individually. For server wide solution follow the steps from the SSH Terminal section below:

Log into Plesk
Go to Service Plans > Example Plan > Web Server > Additional Apache directives
Enter the desired directives in the Additional directives for HTTP and Additional directives for HTTPS fields
Scroll down and click on Update & Sync

Note: All newly created domains will receive the specified settings. Existing domains will not be updated. Additional directives set for already existing domains should be changed on a per-domain basis.

Connect to the server via SSH
Create a configuration file for the directives:
- Debian-based OS (e.g. Ubuntu, Debian):
  
  # vi /etc/apache2/conf-enabled/zz011_custom_directives.conf
- RHEL-based OS (e.g. CentOS, RedHat):
  
  # vi /etc/httpd/conf.d/zz011_custom_directives.conf
Note: Apache loads configuration files in alphabetical order, so if it's required to overwrite some values managed by Plesk, make sure the new custom config file is loaded after zz010_psa_httpd.conf. For example by naming it as zz011_custom_directives.conf
Add the desired Apache directives to the newly created file and save the changes
Check if the Apache configuration is correct by executing this command:

# apachectl configtest

Expected output:

# Syntax OK
Restart Apache by executing this command:
- Debian-based OS:
  
  # systemctl restart apache2
- RHEL-based OS:
  
  # systemctl restart httpd
