Android Enterprise vs Samsung Knox Question

We're an Intune shop (and Govt. agency) with 35 Samsung (Android 10) mobile phones . Our security folks aren't particularly excited about the https://docs.microsoft.com/en-us/mem/intune/protect/data-intune-sends-to-google InTune sends to Google once Android Enterprise is enabled (or the https://docs.microsoft.com/en-us/mem/intune/enrollment/connect-intune-android-enterprise - see par. 2 far right). Is Samsung's Knox something that can be used in lieu of Android Enterprise? I know there's overlap in API's and features but we're wanting to maintain the ability to govern PINS and passcode policy w/o having to expose metadata (even if it is cryptic or inconsequential). Microsoft Enterprise support referred us to Samsung on this one. Waiting to hear from them also. Thanks.
