How could NDIS protocol driver get signed for Win7?

Microsoft has deprecated cross-signing. By following its guide “If your driver runs on Windows 7, 8, or 8.1, your driver must be signed through the Windows Hardware Compatibility Program. To get started, see Create a new hardware submission.”

For Windows7, I must create and submit an .hckx file with HCK studio. But there is no test in the playlist of HCK for a NDIS protocol driver. So How could I get my driver signed?

FYI, in HLK 2004, there are 2 tests automatically listed for my driver by HLK studio. “HyperVisor Code Integrity Readiness Test” and “TDI filters and LSPs are not allowed”.

Any help will be appreciated.
