Disable Cached Exchange Mode on Terminal Server

I am unable to find the administrative templates to disabled Cached Exchange Mode on a WS2025 TS I am deploying. Are these baked into some other area or is this no longer possible?

When I go searching for the templates I reach a 404 page from this URL: https://www.microsoft.com/en-us/download/details.aspx?id=49030&msockid=38de9113e6aa6e0531518724e7b66fc5

I recall needing administrative templates at some point, but am starting to wonder if I am misremembering that. Edit** after multiple days of the URL giving a 404 it is available again.
