Hi,
sorry this is not possible because Easy Profile extends Joomla user profile.

To do this you can
- remove "Edit Profile" button with template override (you can copy /components/com_jsn/views/profile/tmpl/default.php into /templates/your_template_folder/html/com_jsn/profile/default.php)

- Now edit profile link is gone but if you know joomla you can access to edit profile page directly with link, so you need to create a simple system plugin to block this page, you can insert some code like this:

public function onAfterRoute()

{

    if(JRequest::getVar('option')=='com_users' && JRequest::getVar('layout')=='edit') die();

    if(JRequest::getVar('option')=='com_users' && JRequest::getVar('task')=='profile.save') die();

}

or you can make some Joomla hack

To do this you need PHP and Joomla knowledge
