Why is HDRP missing Heightmap?

I tried to look in every shader for an option for Heightmap, there was nothing. Only in the standard shader (pink btw) there was heightmap, but i cannot use it since it was pink. Is there an option for Heightmap in the High-Definition Rendering Pipeline? I made these textures as: AO, Diffuse, Height, Normal, and smoothness. Please help me find heightmap if it even exsists
