Introduction
cPanel will automatically issue and install hostname certificates.
If you choose to install your own hostname certificate, you may disable cPanel's automatically issued hostname certificates to prevent your custom certificate from being overwritten.
Procedure
1. Login to the server via SSH or terminal as the root user
2. Issue the following command as the root user to generate the required touch file:
touch /var/cpanel/ssl/disable_service_certificate_management
That is all that is required to prevent cPanel from issuing and installing the free hostname certificate.
