This might help you You can use the :on keyword when setting up the validation
So in your model, I assume you have something like:
code :
validate :codigoDuplicado?
validate :codigoDuplicado?, on: :create

seems to work fine By default, FluentValidation uses Continue cascade mode for invoking validators in rule definition (i.e. it invokes all validators). You should use StopOnFirstFailure mode to stop execution after first validator fails:
code :
ValidatorOptions.CascadeMode = CascadeMode.StopOnFirstFailure;
public class RequestValidator : AbstractValidator<Request>
{
   public RequestValidator()
   {
       CascadeMode = CascadeMode.StopOnFirstFailure;

       RuleFor(req => req.param1)
          .NotEmpty().WithMessage("param1 is missing.")
          .Must((req, param1) => IsValidRequest(req)).WithMessage("Invalid request.");
       RuleFor(req => req.param2).NotEmpty().WithMessage("param2 is missing.");
       RuleFor(req => req.param3).NotEmpty().WithMessage("param3 is missing.");
   }
}
When(req => !String.IsNullOrEmpty(req.param1) 
         && !String.IsNullOrEmpty(req.param2)
         && !String.IsNullOrEmpty(req.param3), () => {
     RuleFor(req => req.param1)
        .Must((req, param1) => IsValidRequest(req)).WithMessage("Invalid request.");
});
 private bool AllParametersSpecified(Request req)
 {
     return !String.IsNullOrEmpty(req.param1) 
         && !String.IsNullOrEmpty(req.param2)
         && !String.IsNullOrEmpty(req.param3);
 }
When(AllParametersSpecified, () => {
     RuleFor(req => req.param1)
        .Must((req, param1) => IsValidRequest(req)).WithMessage("Invalid request.");
});

seems to work fine I think you can use $user->isAttributeChanged('username');
