How to remove a query string from url and log the result?

How to prevent IIS to log a query string (XYZPassword=1234567) at cs-uri-query? For example: 

userLogin=user1234567@xyz.xpto.pt&page=100&site=xyz.xpto.pt&limit=10&XYZUsername=homepage@xyz.xpto.pt&XYZPassword=1234567

The query string to log should be:

userLogin=user1234567@xyz.xpto.pt&page=100&site=xyz.xpto.pt&limit=10&XYZUsername=homepage@xyz.xpto.pt

 Is that possible with advanced logging?

 thanks,
