The Tathagatagarbha itself is the unattached mind, abiding in no worldly phenomenon whatsoever. It inherently possesses no marks of the mundane world, let alone the four marks. It is the conscious mind that needs to break through attachments to marks; it is consciousness that grasps at appearances; it is consciousness that abides in objects. Spiritual practice involves reducing the conscious mind's attachment to and clinging upon worldly phenomena, diminishing its preoccupation with and attention to worldly matters. Naturally, upon breaking through the four marks, it becomes easy to realize the Tathagatagarbha. Realizing the Tathagatagarbha simultaneously entails breaking through the four marks.
