Hi @Mohammad Abu-Rahmeh ,
By Default, the ability to download attendance report as a Meeting Organizer is enabled. If its disabled, which means your admin has set a Meeting Policy in Teams Admin Center which can be changed by Admin using Teams Admin Center or PowerShell. Therefore, this is currently not possible by Graph API.

If you are looking for a Graph API to get Attendance reports of an Online Meeting, Please refer to this documentation.
Hope this helps.
