Hello @Toh ,
Thank you for posting here.
After my view, I can indeed see a lot of GPO settings are "Intentionally blank" in the document (CIS_Microsoft_Windows_10_Enterprise_Release_20H2_Benchmark_v1.10.0).
my discussion with my colleague, for the GPO settings are "Intentionally blank", maybe Microsoft's recommendation for these settings are "undefined", you can keep it blank or set them depending on your company's requirements if needed, before seting them, you need to download the corresponding ADMX\ADML.
Should you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
