@Jim Brooks, Thanks for posting in Q&A. For the download url, it seems to be archived and not available now. So we can't access it.
To configure policy, in general, we will first check if it has the setting in settings catalog policy in Intune.
If not, then we can check if the ADMX templates are available on the Internet. We can search directly with the template name. In addition, if one device is with the policy setting in GPO, you can also find the administrative template under its C:\Windows\PolicyDefinitions.
Hope the above information can help.
