@Sandip Tawade Thanks for posting in our Q&A.
For this issue, I have checked the settings in intune. Currently, there is no setting that can allow cellular data always on.
Please understand that what intune can do to android device is based on what android MDM provided. It is suggested to contact Android MDM support to confirm if there is such feature provided. Then intune will have a chance to add this feature.
Thanks for your understanding.
