RB5 (QRB5165) Concurrent camera support?

I hope someone can help clarify this. The QRB5165 is advertised by Qualcomm as having support for 7 concurrent cameras, but at the same time only lists the ISP as ‘dual’ and only shows resolution and frame rate limits for up to dual camera setups. What’s the real deal here?

Would the RB5 be able to support 3 or more cameras active at once using the ISP CV features? Object classification / 3D (stereo) vision mainly.
