Is this dropdown showing an enumeration or associated objects? If it is an association, you can not just hide options. If it is associated objects, you can define the selectable objects in the properties. This can be done by xpath or a microflow (nanoflow).
Please, could you describe your case a bit better and propably add a screenshot? Thanks
