When I inquired about this matter to Google, I received the following response.

To prevent in-app purchases from displaying in-app purchases in the Play store,
Remove com.android.vending.BILLING permission in manifest.

Is it possible to set monaca?
Also, if there is any other way, could you please let me know?
