You can achieve this behavior by defining subcube properties in the shared context of your cube definition and explicitely list all the measures that you want to be available for the users
For instance the definition below will only show Yield Curve.TenorDetail and no other measure:
<sharedContexts>
<subCubeProperties isAccessGranted="true">
<grantedMeasures>
<measure>Yield Curve.TenorDetail</measure>
</grantedMeasures>
</subCubeProperties>
</sharedContexts>
