Does using Endpoint Protection also require "Software Updates" to be enabled in Custom Client Settings?

I am managing System Center Endpoint Protection updates on our Windows Server machines, (some 2008 R2, 2012, and a few 2016). (our workstations are using a third party AV). I enabled Endpoint Protection in the Custom Client Settings but I am trying to get the definitions to update regularly.

I have a ADR set up to look for new definitions after a Update Sync, and then to deploy definitions to these clients ASAP, but they aren't pulling the updated definitions after the ADR runs. At this point I'm wonder if in order to allow the ADR to work, does the Custom Client Setting for these servers have to also include the "Software Updates" so it knows to look for updates deployed to them?

Currently the Custom Client Settings are as follows: Client Policy, Computer Agent, Endpoint Protection. I think given the nature of using an ADR, I would need the clients to know to check in for anything an ADR has ready for them.

Thanks for any info/assistance!

Edit: corrected my server OS's.
