Yes, you can point a Parked domain to a specific folder.
To park a domain in the cPanel, you need to log into the cPanel. For the same, you need to use cPanel's feature called "Parked domain".
This feature allows you to point a domain to your main site /public_html folder. However, this will not keep the parked domain name in the URL. You will be redirected to a subfolder for the main domain.
To have a domain name pointed to a specific subfolder, you need to configure the domain as Addon Domain.
