We have a Connect-Rest rule which uses MIME type. When we used this service in Pega 7.1.9, we customized pyRestInvokeConnector to add that to the entity.
Currently we upgraded to 8.4.4 and i think Pega product supports this MIME type, but need to understand how to configure MIME types in Pega 8 version.

Do you mean using multipart/form-data for attachments in Connect-Rest? Please refer the excerpt from Pega help on how to do it.
When building the outbound message content for a REST, SOAP, SAP, dotNet, or HTTP connector, Pega Platform looks for a top-level clipboard page named pyRequestAttachmentPage of type Data-ServiceMessage. If it finds the page in the clipboard, it adds attachments to the outgoing message for every string value found in the pyAttachValues Value List property on the page. Each string is assumed to be a Base64-encoded representation of a binary data value. This page must be created and populated prior to invoking the connector.
