How to enable shell_exec() for a specific domain?

Question

PHP

Given. Server with isp panel. By default, as on many servers, many "dangerous features" are disabled. This is done in php.ini which is responsible for the entire server and is located at /etc/php5/apache2.
There are many users and many domains on the server. You cannot enable this feature for the entire server. Must be enabled for a specific domain. The php settings are set for the domain as an apache module. i.e. cgi is disabled. accordingly, you cannot put your php.ini in the folder with the domain. Are there any solutions?
