Yes! You can make pumpkin rolls ahead of time!
Method 1 is making the dough, covering it in a bowl with plastic wrap and allowing it to sit in the fridge over night. The next day, set the bowl until no longer chilly and proceed as normal.
Method 2 is to allow the dough to rise, roll out the dough on a cookie sheet and then cover in plastic wrap and rest in the fridge overnight. Place on the counter to take the chill off for an hour or two and then bake.
