Tracker Preferences Registry Keys

Hi,

There is a vendor that we work with as our primary system that has some recommendations on Adobe Acrobat Reader (we're mostly using DC at this point) settings that we'd really like to adhere to.  I tracked down registry keys for all of them but two and have them going out via GPO.  I am stuck on these last two though and really need to figure it out.  Within Edit -> Preferences -> Tracker, I need to set "Automatically Check for New Comments and Form Data" to Never and "Suspend the Check for New Comments and Form Data" to After 30 days of inactivity.  We have a pretty good amount of users, so going around and manually setting this isn't possible.  I've done a ton of Googling and digging through the registry, but I'm coming up empty-handed.  Does anyone know what registry keys are associated to these preferences?

Thanks.
