You could try and populate a MATCHES Regex condition or follow another suggestion from this thread:

REGEX TO FILTER MULTIPLE STRINGS IN A FIELD

Hello - I am attempting to use RegEx to filter 4 specific strings from a field in my data. The field is string, and the unique values are 11, 12, 13, 21, 22, 23, 31, 32, 33. I am trying to filter out all rows that have 11, 12, 21, or 22. I have not used RegEx for this before, any points on how I can accomplish this? [regex] Thank you for your time, and I hope you all are well!!

At the end there also is a sample workflow. I am on a mobile so I have not checked it myself yet.
