@yeooandyni, Thanks for posting in Q&A.
Based on my research, Update Ring Profiles control how and when devices receive quality and feature updates, including settings like deferral periods and restart behavior.
Feature Update Policies allow you to specify a target Windows version to which devices should update, they provide granular control over which devices receive specific feature updates, ensuring that only designated devices upgrade to a particular Windows version.
So, we can create Update rings policy and feature update policy at the same time and control which device can upgrade to Windows 11. And please ensure turn off Upgrade Windows 10 devices to Latest Windows 11 release" in update rings policy, configure which windows 11 version you want the devices in security group to upgrade in feature update policy.
Here are the upgrade requirements you can refer to.
