Unfortunately it still requires a Wi-Fi adapter:
It is important to note that Miracast over Infrastructure is not a replacement for standard Miracast. Instead, the functionality is complementary, and provides an advantage to users who are part of the enterprise network.
Discovery requests to identify Miracast receivers can only occur through the Wi-Fi adapter. Once the receivers have been identified, Windows 10 can then attempt the connection to the network.
Wow, that's an insane software design choice.
edit: looks like there's support for Miracast over Ethernet at least in Windows: https://learn.microsoft.com/en-us/surface-hub/miracast-over-...
