stop sending email to setTargetobjectId in single email message even using Email template

child__c (child) is custom object Contact (parent) lookup relationship.
i need to send a mail to email field which is present in child object with email template.
when ever we are using Email template setTargetObjectId is mandatory .
if our requirement is like we dont want to send mail to TargetObjectId , only need to send to email field which is present on child object.

to achieve this we need to use setTreatTargetObjectAsRecipient(false) Boolean method so it will stop sending email to TargetObjectId .


Required if using a template, optional otherwise. The ID of the contact, lead, or user to which the email will be sent. The ID you specify sets the context and ensures that merge fields in the template contain the correct data.


Optional. If set to true, the targetObjectId (a contact, lead, or user) is the recipient of the email. If set to false, thetargetObjectId is supplied as the WhoId field for template rendering but isn’t a recipient of the email. The default is true.


public void setTreatTargetObjectAsRecipient(Boolean treatAsRecipient)
