You can set metadata on the blob before calling to upload.
You can see the available response ( metadata) that is available for the blob: https://learn.microsoft.com/en-us/rest/api/storageservices/get-blob-properties#sample-response
You can leverage Get Blob Metadata and Set Blob Metadata REST API to understand which metadata are default and which can be tweaked.
Since you are uploading via Dynamics you will need to see if the metadata added is a match for the Azure Blob side. I recommend reaching out via the Dynamics 365 community forum to see how metadata is added on their side.
