Processing components to manufacture information handling systems have build-to-order integrated circuits with plural selectively-enabled features set at the information handling system manufacture location. For instance, fuses integrated in the integrated circuits are selectively blown at the information handling system manufacture location to permanently disable features so that the processing components have a desired configuration. As another example, feature enable or disable states are programmed in flash incorporated in the integrated circuit, with the flash programmability subsequently disabled to permanently set the features so that the processing components have a desired configuration. Features are set with keys provided by the processing component manufacturer to track the information handling system manufacturer's use of the features.
