Does Network Perimeter Restrict EPM Endpoints

With Oracle deprecating the setIPAllow list command in EPM, we are in the process of setting up a network perimeter in OCI and applying this to our EPM environments. From what I am understanding, a network perimeter only applies to the sign on policy tied to the applications. Does this also restrict any API calls that are made to the URLs? The previous functionality restricted the entirety of the URL and blocked API calls. This is a much larger necessity to have in place.

If not, what is the process to restrict our endpoints from API calls outside our perimeter?
