Run DAX expression conditionally

Let's say I have the following expression:

EVALUATE SUMMARIZECOLUMNS('RealTimeServiceTypeSummary'[PointCount], 'RealTimeServiceTypeSummary'[RealTimeServiceTypeName])

This expression is a query for a dateset. What I want is to run it conditionally meaning it either returns data or not doesn't event run.

 

Thanks

@Markzolotoy try this:

 

 

DEFINE
VAR __RunQuery = FALSE () --set value to TRUE () if you want to run the query
EVALUATE 
SUMMARIZECOLUMNS(
   'RealTimeServiceTypeSummary'[PointCount], 
   'RealTimeServiceTypeSummary'[RealTimeServiceTypeName],
   FILTER ( 'RealTimeServiceTypeSummary', __RunQuery )
)

@Markzolotoy Under what condition would it not run?
