For now I would shut off the current "warm side" UTH, and leave the "cool side" UTH settings alone as it'll be fine as the warm side. Over the winter if your room temperature drops and you have a hard time maintaining the ambient temp, you can turn the unused UTH back on, but set so that it's around 80*F.
ETA: Looks like we were both posting at the same time. I would set the warm side UTH so the glass is no hotter than 93*F, and the cool side so the glass is around 80*F, since your snake likes to burrow down and lay on them.
