Answer

Log in to Plesk.
Install the extension Panel.ini editor to manage Plesk settings.
Go to Extensions > My Extensions > Panel.ini Editor (Open button) > switch to the Editor tab.
Add the following lines at the end of the file:

[webserver]
xPoweredByHeader = off
Click Save.
Go to Tools & Settings > Diagnose & Repair and click repair for Web & FTP Servers to rebuild web-server configuration.

Command-line solution

Connect to the Plesk server via SSH (Linux) / RDP (Windows Server).
Open panel.ini file with the command (on Windows Server, use a command prompt):

# plesk conf panel.ini
Add the lines below at the bottom of the file:

[webserver]
xPoweredByHeader = off
Save changes and close the file.
Recreate web-server configuration for domains:

# plesk repair web -domains-only
