If you are able to modify the Object code in control builder then you can set the property permissions there on the object type. ( Its an item in one of the control builder menus when you have the program open for editing. ) You need to do this in the POU where the HSI datatype is declared
If you cannot edit the variable type definition or you want to change the setting for just one object instance then use a "Property Attribute Override" aspect. Place it on the object type if you want to override all objects or just on any instances that you want special permissions for.
Note that property permissions are set for each individual component of a user defined data type. (ie for every HSI.property) not the HSI
