Not really. I think you found the Patch + Parameters support: https://github.com/medplum/medplum/pull/5317/files But that's only syntactic sugar around a Patch operation (the alternative is to Base64 encode the JSONPatch JSON) Our Patch operation is currently a very thin wrapper around the

rfc6902

library (https://www.npmjs.com/package/rfc6902). Full FHIRPath Patch has quite a bit more complexity, and would be non-trivial lift 😢
