need help with textures sample/object

hi I would like to know if is there a way to have a texture sample at start and texture object as output.

here is what i want to do,


i’m actually creating a custom material for a planet but i only have the possibility to use texture object as input, and i want to use Parallax Occlusion Mapping (POM), but POM is only compatible with Texture Sample For UV’s

i really don’t know what to do or am i just blind?

if you can help me that would be appreciated.
