Hide Blueprint variable from "EditInlineNew" clsses

Hi

I have this class:

UCLASS(Abstract, Blueprintable, EditInlineNew, DefaultToInstanced, CollapseCategories)
class URangedWeaponFiringMode : public UObject
{
...
}

And I created a BP that inherits from it.

The highlighted variable are marked as “Private” and not “Instance Editable”, but they’re still being shown up when adding this BP to my Data Asset:

Is there a way to hide them?
