@Van M Hasan, Thanks for posting in Q&A.
From your description, I know you want to rename your android device.
Based on my research, Device administrator enrollment method is not in the support list of renaming devices in Intune portal.
If you change device name on the device, it will not sync the changed device name with Intune, or if you change device name through company portal, it just shows the changed display name on company portal but still not sync with Intune.
So, it is suggested that you unenroll the device and try to re-enroll using Android Enterprise which support rename device.
Here are some links about how to enroll device using Android Enterprise and Rename device.
- Android Enterprise corporate owned dedicated devices (COSU)
- Android Enterprise corporate owned fully managed (COBO)
- Android Enterprise corporate owned work profile (COPE)
