Does overriding UnityWWWRequestDefaultProvider works for UnityWebRequest?

My project suffers from web cache problem in iOS client. We used UnityWebRequest with

SetRequestHeader("Cache-Control", "max-age=0, no-cache, no-store"); SetRequestHeader("Pragma", "no-cache");

but it does not works well.

I found that overriding iOS native function which used by unity : https://docs.unity3d.com/Manual/iosCustomWWWRequest.html

but it says this sample works for WWW class (not UnityWebRequest class).

I want to know that whether this sample works to UnityWebRequest too.
