An infrastructure admin wants to restrict installing Portworx in two nodes.

Comprehensive and Detailed Explanation From Exact Extract:

Restricting Portworx installation on certain Kubernetes nodes is achieved by labeling those nodes with px/enabled=false. This label signals the Portworx Operator or installer to exclude these nodes from Portworx deployment. This allows admins to reserve nodes for other workloads or prevent Portworx from running on unsupported hardware. The label px/service=stop or px/storage-node=false are not recognized controls in the Portworx installation process. Portworx deployment guides consistently document the use of px/enabled=false for node exclusion, providing a simple, declarative way to control cluster topology and resource assignment during Portworx installations and upgrades【Pure Storage Portworx Deployment Guide†source】.
