I got it working by setting the modeNullable to true.
<cf:method name="Load">
<cf:body text="LOADONE(date startDate, date endDate, bool includeAgeSeventeenAndUnder, bool includeAgeEighteenAndOver,int sisProgramId) RAW " rawText="This has been deleted because it is not relevent to question" language="tsql" />
<cf:parameter typeName="bool" name="includeAgeSeventeenAndUnder" modelNullable="True" />
<cf:parameter typeName="bool" name="includeAgeEighteenAndOver" modelNullable="True" />
</cf:method>
Meziantou suggestion is actually preferable since I really don't want the parameters to be nullable. The below snippet demonstrates the correct way to disable the default value check.
<cf:method name="Load">
<cf:body text="LOADONE(date startDate, date endDate, bool includeAgeSeventeenAndUnder, bool includeAgeEighteenAndOver,int sisProgramId) RAW " rawText="This has been deleted because it is not relevent to question" language="tsql" />
<cf:parameter typeName="bool" cfom:checkDefaultValue="false" name="includeAgeSeventeenAndUnder" modelNullable="False" />
<cf:parameter typeName="bool" cfom:checkDefaultValue="false" name="includeAgeEighteenAndOver" modelNullable="False" />
</cf:method>
