HI
1.can you dynamically add to the size of the pool or do you need to setup a separate capacity pool?
yes, we can dynamically add to the size of the pool, but resizing the capacity pool changes the purchased Azure NetApp Files capacity.

2.Can you dynamically add to the size of the pool?
There is ANFCapacityManager.It is an Azure Logic App that manages capacity-based alert rules. It automatically increases volume sizes to prevent your Azure NetApp Files volumes from running out of space.
What changing to volume hard quota means for your Azure NetApp Files service

3."Finally, would it be recommended to setup a new, larger capacity pool and migrate all the profiles to it"
"In the case of automatic QoS volumes, if you are considering assigning volume quota amounts beyond 70.31 TiB, additional quota may be assigned to a volume for storing additional data. However, the added quota will not result in a further increase in actual throughput."
since your azure netapp file is smaller than 70.31 TiB, so setuping a new, larger capacity pool and migrate all the profiles to it is better.
