Surely but as mentioned in the documentation link you shared it is also specified in the “Limitations” section
REST API feature supported on X86 only.
So my question is about whether or not this limitation is due to the current stage of development or if Nvidia has (or not) plans to make it available on DeepStream for Orin (and ARM64) based hardware either maybe later on.
As we are interested by such capabilities for our Orin based hardware I would like to consider Nvidia option as a candidate if it is compatible in the next released versions.
