Anyone know how to modify these via gpo or registry? I can't find the keys anywhere.

Copied from Google. The GPO path is: Admin Templates > Windows Components > File Explorer > Default Associations Configuration File You would point that to a network path of the XML file You can look at C:\Windows\System32\OEMDefaultAssociations.xml for a reference You also can use WEM.

@Jeff Riechers these are indexing properties. I don't think they are stored in the associations file. Checking the path I don't see anything regarding these. I've had a lot of trouble finding where windows technically stores them.

You may be able to find them yourself using regrecent or any similar tools that can record changes made in registry. Run regecent, change one of the settings, and see what changed in the registry

Looks like those are stored in the Index database itself. This article goes into detail on the DB location. https://devblogs.microsoft.com/windows-search-platform/configuration-and-settings/#:~:text=Index%20Location,the%20indexing%20service%20files%20there.

@Jeff Riechers thanks. I'll have to take a look. I'm looking to set indexing only properties for pdf as it's causing delay in users logging out.

Are they non-persistent machines? If so I would just disable the Search and Indexing process, as that database is going to get recreated on every reboot. If they are persistent, then I would work to setup the process locally as it will be shared for all users. Also, you don't have to worry about remote files, as those can't be indexed by Windows unfortunately.

@Jeff Riechers yes non-persistent.
