Can I dynamically hide a column in the tablix without calling the stored procedure associated with the dataset when a report parameter changes?

I have an SSRS report that has a parameter "RptParms" that allows multiple values to be selected by the user.  Example values are 'AAA', 'BBB', 'CCC', and 'DDD'.

When the user selects "View Report" a stored procedure is run that returns 100 rows of 10 columns each to the dataset.

After the data is returned and when the user then selects 'CCC' as one of the parameter choices I want to hide 2 of the columns without calling the stored procedure again to return the 100 rows.

The visibility expression for these 2 columns will produce code for the RDL similar to the following:

              <Visibility>
                <Hidden>=iif(Filter(Parameters!RptParms.Value,"CCC").Length&gt;0,true,false)</Hidden>
              </Visibility>

Can I dynamically hide these 2 columns in the tablix without calling the stored procedure associated with the dataset when a report parameter changes?

Thank you for your assistance.
