@Srinivas Pasupuleti - CyberSecurity, Thanks for posting in Q&A. From your description, it seems you want to change the Microsoft Entra registered device to Microsoft Entra Hybrid joined. and enroll into Intune. Based on my experience, there's no direct way to do. You need to remove the device from Intune firstly and re-enroll. To retire these devices from Intune, we can choose retire action in Intune portal.

And you can retire devices in bulk.

After that, ensure all the Microsoft Entra registered devices records are removed in Mcirosoft Entra. if not, delete it in Microsoft Entra portal.

After all the above are removed, we can plan to do Microsoft Entra Hybrid Joined.

As a note, to confirm if Microsoft Entra Hybrid Joined successfully, you can run "dsregcmd /status" and check if AzureAdJoined, DomainJoined and AzureAdPrt are all yes.

Then we can consider doing Intune enrollment. For your scenario, the recommended enrollment method is GPO enroll. Here is a link with more details:

I notice there are 1000 devices you want to change. To avoid any impact, please firstly test on some devices before we do it on all the devices.

Hope the above information can help.
