It can be OK but will restrict the airflow a small amount.
Make sure that it does not pose a fire risk and not too many bends.
It the air is unfiltered then expect a large build up of dirt within the duct.
Local legislation might put restrictions on it.
Here in UK it's pretty standard to use at least some flex to connect the cooker hood with, what the rules say in KSA I do not know.
