While creating change order via API, system is sending FYI notifiation to requester or buyer

Summary:

Hello Experts,

We need to update some attributes on PO Line and we are using API for the same but this process is creating a change order and submitting it. This is also triggering emails to requester or buyer.

For example users received email with subject: FYI: Document (Buyer Change Order) 300xxxxxx Changed )

I'd like to know is there a flag or setting to stop such notification where CO is triggered via API?
