Hello Gokul R Dev,
Thanks for reaching out. The Events endpoint does not have any parameters that allows auto recording of meetings. For online meetings you can set the ' {"recordAutomatically": true} ' parameter in the body of the update onlineMeetings Graph query. You can find more information on updating online meetings in article https://learn.microsoft.com/en-us/graph/api/onlinemeeting-update?view=graph-rest-1.0&tabs=http.
