isEmailBounced, can field be changed?

Hello,

I just discovered there is a isEmailBounced field on Salesforce contacts records. This field is not in the UI/UX is another of the hidden fields in Salesforce only available in reports (this one particularly only available in classic reports).

We use an external emailing tool which records if emails are bounced or not. I'd like to feedback that into Salesforce. I'd like to know if this field can be changed so that it can be updated if mapped?  When I try to update a small handful of contact records via an external tool I got "Unable to create/update fields: IsEmailBounced. Please check the security settings of this field and verify that it is read/write for your profile or permission set."

Perhaps this is Email Bounced field, is a system field which only is set to TRUE for emails sent from Salesforce?

Thank you!
