Does any USB 3 dock support HDCP - if so, which units?

[Philomorph]

Hi all, I'm new to DisplayLink and USB docks, but I've been unable to find a definitive answer, so hoping you can help.

I have a new Lenovo Flex-5 Windows 10 laptop. It has a USB-C port, but they apparently only made it to support data, so all the new USB-C docks don't work with this model for video I even tried a few just to confirm this.

It's got USB 3.0 ports so I figured I'd get that kind of dock. But now I can't seem to find one that says explicitly that it supports HDCP so I can stream Netflix to an external monitor.

The DL spec page for the newer chipsets indicates a lot of them support HDCP, but the vendors I've asked so far don't seem to know which chipset they are using or what they support, so...

Hopefully a simple question - does there exist a USB 3.0 dock that will support HDCP so I can stream Netflix/Amazon to an external monitor, or am I out of luck?

Thanks!
