My question is Can ectotherms undergo vasodilation/vasoconstriction.
Also can ectotherms sweat, shiver and move hairs up and down
I think only endotherms can do this but just checking to make sure.

No, vasodilation and sweating are a part of thermoregulation, which ectotherms don't do seeing as their body temperature matches the environment. Then have no sweat glands.
I think they can shiver though (if I remember rightly) although I'm not sure...

Ectotherms depend mostly on heat gain and loss through the environment. They don't need to dp vasodilation or constriction to regulate heat loss. I don't know whether they have one or lack a pervisceral nervous system. If so, they might do it pretty well without these processes.
I don't think they shiver as well. Ever seen a snake out there in the cold, shivering? :P
