iOS Filtering with Defender Endpoint According to App

Thanks, Moe! Those are helpful links. However, I'm past those steps. But I'm probably not being specific enough. I would like to

- Install a mobileconfig that instructs Defender to allow only a whitelist of URLs

- But specify Safari as exempted from that profile/whitelist.

 This is possible, in general, when specifying a third-party content filter in Apple Configurator. Using this method, it allows you to exempt certain apps from the filter. I'm wondering if it's possible to specify Defender as that third-party app . . . 

Thanks.
