Answer

To enable HTTP/2 support for Nginx:

1. Connect to the server using SSH

2. enable HTTP/2 with the following command:

   # plesk bin http2_pref enable

   Note: During this step nginx web server will be tuned to use the TLS protocol with modern and secure ciphers, the whole web server configuration will be rebuilt, and all client’s sites with ‘SSL Support’ will be moved to HTTP/2.

Note: HTTP/2 can be  disabled with the following command:

# plesk bin http2_pref disable

Note: HTTP/2 support is a server-wide setting and cannot be set for specific domains only
