Provide IDirect3DDeviceManager9 from Custom Media Sink

I am writing a custom media sink to render video to a device, following the example of the WavSink.

Now how to proceed if I want to use DirectX surfaces for carrying video frame samples? As far as I know, the EVR renderer is usually providing IDirect3DDeviceManager9 interface, which is assigned to the MFTs by the topology loader.

Since I am not rendering on EVR, but on my sink instead, how can I create such IDirect3DDeviceManager9 instance to provide to the topology loader?

Does anyone know articles or resources describing such scenario?

Thanks for any help.
