entityref_formatter_access_bypass

The Entity reference formatter access bypass module extends the Entity view
reference formatter and allow to select a view mode as fallback in case a user
cannot access to an entity.

By default, if a user cannot access to an entity, the entity will not be
displayed.
With this fallback setting, entity can be displayed in specific view mode to
display only data the user can access.

Configuration

Choose 'Rendered entity with access bypass fallback' formatter in Entity
reference and configure both default view mode and fallback view mode.
