how to disable response buffering in a way it is affecting to a particular URL or PHP file in Windows IIS server?

We are trying to disable response buffering in the IIS server, but not to affect across the system, only for one particular URL. is that possible to achieve this?

<add name="PHP_via_FastCGI1" path="*.php" verb="*" type="" modules="FastCgiModule" scriptProcessor="C:Program FilesPHPv7.4php-cgi.exe" resourceType="Either" requireAccess="Script" allowPathInfo="false" preCondition="" responseBufferLimit="0" />

When we use the above configuration in web.config file, we noticed that we can disable the response buffer, but it was affecting across the application. not to a specific URL.

Can someone please help me with this?

Regards
