Question about Minifilter Driver Release

I have completed the development of a minifilter driver.

To release the driver, is the following process correct?

1. Obtain an EV Code Signing Certificate.
2. Conduct HLK (Hardware Lab Kit) testing.
3. Create a CAB file.
4. Submit the test results and certificate to Microsoft.
5. Release the minifilter driver.

Additional Question:

For Windows 10 and Windows Server 2019 or later, is it mandatory to obtain an EV Code Signing Certificate?

Let me know if you need further refinements!
