Thanks. Most users are Mac though, so that’s not going to work for us… 
I’ll look into if there is an equivalent. Many users are not employees but rather consultants and vendors. So deploying won’t work.
For Mac, I’m sure there is a plist equivalent, but I haven’t bothered with it as we have a very small percentage of Mac users.
Consultants and vendors are functionally the same as supporting BYOD environments. I would push to move their connectivity to something like a ZeroTrust solution (Azure App Proxy etc.) wherever possible.
You don’t want a vendor compromise to propagate to your environment.
