Need Separate Cpanel for Each Domain - Linux Hosting

I am using ZeroSSL to create my SSL certs at no charge.  I have more than one domain, each of which must have a separate certificate.  The only caveat is that ZeroSSL looks in public_html for the files it needs and I have my second domain as an addon domain so it's public_html is not in the root directory.

 

Therefore I need each of my domains to have a separate cpanel  so that each domain will have a root public_html.  

 

How can I set up each of my domains in a separate cpanel?

 

Thanks!
