Currently, it is not possible to limit the number of pipelines shown in Jenkins pipelines based views (implemented in WorkflowPipelineView). This is an option that is available for views based on traditional build jobs chained together with downstream dependencies (implemented in DeliveryPipelineView). This configuration is particularly of interest when combined with e.g. sorting functionality to limit the number of pipelines shown in the view (e.g. when displayed on a big screen TV).
