Hello Bikram Jeet Singh,
Thank you for reaching out to Microsoft!
It seems like you need to create a reply to a conversation without triggering email notifications to the group mailbox. Unfortunately, the Microsoft Graph API does not provide a built-in way to suppress email notifications for replies to conversations. We would recommend you submitting a request in the feedback portal mentioned below:

Additionally, you can try the workaround which might help resolve the issue:
Try modifying the group's settings to prevent sending emails for conversation replies. This is a global setting and will affect all conversations within the group.
Instead of using the conversations
endpoint, could you try using chat or channel endpoints within Microsoft Teams, which provides more granular control over notifications.
Hope this helps.
