As a standalone noun without 'zur', 'die Verfügung' (order/injunction) is a formal term from legal and administrative language. It refers to an official order.

The city issued an order to protect residents from noise.
The expression 'die Verfügung über etwas haben' (to have control over something) means to have the control or the right to use something. It is always used with the preposition 'über' (over/about) and the accusative.

After the death of the parents, the eldest son had sole control over the assets.
ban / prohibition
A Verfügung is an official, usually written order or decision issued by an authority or court. A Verbot, by contrast, refers to the content of a rule: something is not allowed. A Verfügung can therefore contain a Verbot, but it does not necessarily prohibit anything.

Für das Grillen im Park gilt seit heute ein offizielles Verbot.
