Hi @EmilyB,
Welcome to the DocuSign Community — we’re really glad to have you here!
DocuSign eSignature currently doesn’t support P7M/CAdES signatures. However, DocuSign does partner with ITAgile (TSP in Italy), which can possibly handle this type of workflow. If this is something you’d like to explore further, I’d recommend connecting with our Sales team 👉 Talk to Docusign Sales | Request a Demo or Pricing.
Regarding your second question, it is possible to use a qualified digital certificate stored on a USB token, provided it is issued by a trusted EU issuer. This works through DocuSign’s signer‑held EU QES capability. The key thing to note is that the resulting signature will be in PAdES format (a digital signature on a PDF), not CAdES (Digital signature on a CML file).
For reference:

Hope it helps clarify things. Let us know if you have questions—we've got you!
