I'm not even sure if this is a supported feature but I stumbled across the following while browsing the repository and testing something out of curiosity:
https://github.com/openshift/cluster-node-tuning-operator/blob/release-4.14/docs/performanceprofile/configuration_hotfixes.md?plain=1#L11
Annotation on my SNO node, annotation `performance.openshift.io/enable-physical-dev-rps: "true"` gets rid of the `update-rps*.service`, yet my physical interfaces all have an all 0s rps_cpus mask:

Feel free to close this out if this isn't a supported feature
