Hi @Dipika Das ,
Thanks for reaching Microsoft Q&A, Remove from Shared list is based on legacy DocumentSharingManager SharePoint REST API.
Currently there is no equivalent Microsoft Graph API for Remove from Shared list.
The only alternative is DELETE /drives/{remote-drive-id}/items/{item-id}/permissions/{perm-id} refer permission-delete.
I recommend you submit a feature request in graph feedback portal, which will be monitored by Microsoft Product Engineering team and take up for implementation based on number of votes receieved and people requesting for this feature.
Hope this helps.
