Hello Michel Pelletier,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you are looking for how to redact CVV.
It's great to hear that you're happy with the results from using Azure PII recognition! Unfortunately, there isn't a specific entity category for redacting the CVV verification number directly. However, you can use the NumericIdentifier entity category to redact any numeric or alphanumeric identifier, which can include CVV numbers
I hope this is helpful! Do not hesitate to let me know if you have any other questions.
