@Li, Henry, Thanks for posting in Q&A. Unfortunately, at this time Harmony OS is not in our official supported OS list yet:
Intune supports devices running the following operating systems (OS):
· Android
· iOS/iPadOS
· Linux
· macOS
· Windows
· Chrome OS

While we do not take any action to explicitly block HarmonyOS, any issues occurring only on Harmony devices are not eligible for support.
But you can feedback in the following link to see if it can be supported in the future.
