Excluding task(s) from SPI or CPI Calculations

Question

Is there a mechanism to exclude task(s) from being included in the SPI/CPI calculations?
The reason why I am asking this is we want to exclude a couple level of effort tasks from counting for or against the SPI/CPI.
Thanks,
Cheryl

Thank you Prasanna and Guillaume for your input.
Prasanna,
Removing the baselines on the particular task(s) does seem to exclude some of the data from being included in SPI/CPI; however the baseline initially rolled up to the level 0 summary task, so with this approach either the SPI/CPI should be not
be evaluated at the level 0 summary task level.  Instead the values should be viewed for the section of baselined tasks, assuming that the schedule was arranged to isolate the level of effort (LOEs) tasks to not include in SPI/CPI.  To avoid
this issue, at the initial onset of schedule development ensure the LOEs are isolated and NEVER include these in the baseline, even in the initial baseline that way their values are excluded.  The ACWP will continue to get impacted, so CPI will always
be impacted even at Level 0 summary task.  But we have some options, your suggestion allowed us to dig in these.  Thank you.
Guillaume,
We may take a look at this approach, however we rely on the task updates from actuals, so yes does sound like a bit more work.  But thank you for the suggestion.
