How to update expired Certificate for Windows IOT

In our BSP all drivers are test signed currently with whatever certificates are supplied in Program Files(x86)\Windows Kits\10\tool\certificates folder. Some of these certificates expired 2/1/2022 and now PackageGen fails and we can no longer build an FFU. Where do I find the new certificates? I already tried Update for Windows OEM HAL Extension but this does not fix our build issue. I am not experienced with how certificates work or what to do. Can anyone help? We use Visual Studio 2017 for building our BSP.

    One has to purchase a code signing certificate to build a retail version of Windows IoT Core: https://www.annabooks.com/Articles/Articles_IoT10Core/Windows-10-IoT-Core-Sign-and-Build-Retail-Images-Rev1.3.pdf. It has been a while, but from what I remember, the certificate should sign all the packaged (CAB) items that get built into the image.
