Can you move TextMeshPro with Transform, not RectTransform?

Hey guys, very new to Unity and I was wondering how you could change the location of a textmeshpro object with transform coordinates and not the RectTransform, or a way to convert the positioning from one to the other. I want the textbox to sit + 1 y-value above the player character, but my player character is not a UI-gameObject and I want to keep it that way. Any help woud be greatly appreciated.
