Those wouldn’t stop ice daming, those are to stop the snow from suddenly coming off the roof (and onto you).
Ice daming is caused by heat loss near the eaves that causes ice to build up and then “back up” under the singles as it forms and causing leaks inside.
Yes, I guess I should’ve said it’s typically above the exterior walls where the heat loss happens and was trying to keep it simpler with just “near the eaves”, but the melting from the heat loss is what makes the ice and you need the colder area lower on the roof to cause the freezing/daming.
Why not use snow hooks?

The heat loss occurs higher up the roof. The lack of heat loss freezes it at the eaves.
