@Rohanathan Suresh Thanks for posting in our Q&A. I'm not a support engineer of powershell and know little about it. I just solve some problems during the powershell script deployment.
From your description, did you mean that you want to see Space occupied and device information in intune portal? If yes, I think we can check specific device information in Devices > Windows > select a specific device > hardware. Space occupied is also included in the hardware page.
Thanks for your understanding.
