Is it possible to modify published data?

You can always modify the metadata of published data, e.g., update the study description or study status or add new related resources such as recently published journal articles. After uploading your changes, a NFDI4Health data steward will check the accuracy and completeness of the modified metadata. Once everything is approved, your data will be published under a new version, and a new DOI will be assigned. Old versions of your resource will remain accessible.
