It is sometimes desirable to differentially regulate fluid flow in a subterranean formation using autonomous inflow control devices (AICDs), but they are not readily configurable in the field at present. Wellbore systems providing adjustable flow control may comprise: a wellbore pipe having a flow control assembly fixedly coupled thereto, the wellbore pipe having an interior space, an outer surface, and one or more AICDs establishing a fluid connection between the interior space and the outer surface of the wellbore pipe, and the flow control assembly comprising one or more flow chambers defined on the outer surface about the one or more AICDs, one or more inlets being fluidly connected to the one or more flow chambers; wherein the one or more inlets are configured to accept a plug for occluding fluid flow therethrough, so as to limit access of a fluid to an entry location of the AICDs.
