Hi I. Keen to make these hot x buns but want them ready late morning. Could the dough be put in the fridge overnight and if so at what step please? Th

I'd put it in the fridge after shaping, then take out next day and let proof on counter until very puffy. If you want the time on the counter to be a bit shorter, let them sit on counter 1hr after shaping, then into fridge, then finish proofing next morning.
