update internet headers of mail with microsoft graph api

Question

I am trying to edit internet headers of outlook mails of Office 365 using the graph API. But I find that using REST calls to GET

https://graph.microsoft.com/v1.0/me/messages

I can not even get the internet header details of mails (I am getting other fields like body,subject,etc.).

Also using REST call to PATCH

https://graph.microsoft.com/v1.0/me/messages/

I am not able to update internet headers. Is it possible in any way to update internet headers of mail using the GRAPH APIs?
