Currently, API doesn’t support a feature to add password protection to CSV file format. However, we are investigating this scenario. Your investigation ticket ID is MERGERNET-823. As there is any progress, you’ll be notified.

Unfortunately, a CSV file can’t be password-protected because it is a plain text file. As a workaround, you can convert the CSV file to XLSX format and then protect the XLSX file.
