Disable drill for projects

I have created a caculated member for project dimension, it likes below:

The drill functions for both ‘drill into’ and ‘drill across’ are available for the calulated member and its hierarchy projects on the dashboard charts when I use this caculated member to create charts.

And I have tried to use some methods like ‘–annotations.disable_drill=true’ to disabled it, but seems like it only can disable for the caculated member, not for both calulated member and its hierarchy projects.

please help on this, Thanks a lot!
