How to upgrade Vision Programming Interface (VPI) on ZED Box Orin NX16

A newly purchased ZED Box Orin NX has VPI version 2.2.7 which runs with python 3.8. Some algorithms (ORB, stereo disparity) are not working in this VPI version. (They work in version 3)

How do I upgrade to the latest version of VPI 3.1.5?

I tried the installation commands at:
sudo apt-get update
sudo apt-get install libnvvpi3

but got error:
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package libnvvpi3

The ZED box has
Installed: 5.1.1-b56

Hi @pfvideo
VPI is part of the Jetpack package.
You should not upgrade it manually.

I recommend consulting the NVIDIA Developer Forum for more detailed information.
