Signing a Windows Kernel driver without using Microsoft

[Stingered]

I've been doing some reading and reviewed the lengthy process of using MS to get your .CAB file digitally signed and approved (VERY not worth it). Not to mention going through the expensive process of obtaining a code signing cert (not worth it). I know there are "tools" out there to create your own code-signing cert, and/or you can use a leaked cert. My question is how do you do this once you have created/obtained said cert. Can I just use signtool.exe or some other similar tool to do this? I've looked online for a how-to, but it seems my search strings are not doing the job. I hope this enough detail on what I'm asking...

P.S. I'd rather not us a test cert.

-Thx

EDIT:

Well, After doing even more research, I do not think this is possible. There are methods, such as KDMAPPER, but even that has been patched as of Windows 11 22H2.
