I presume this is about Windows. There, Widevine actually isn't running emulated on Arm64 Brave. It's running natively. It's only running emulated on x64 Brave (where all of Brave is running emulated, if you will).

Still, the way we obtain Arm64 Widevine on Windows is very complex, due to licensing restrictions. We should check if Widevine is now available from Google's component update server.
