Downgrade JetPack on reComputer J2011 to 4.4

We need TensorRT 7.1.3 to run our program.
This product has pre-installed JetPack version 4.6, so TensorRT 8.0.1 is installed.
I’m trying to downgrade to JetPack 4.4 to use TensorRT 7.1.3, is that possible?
I found this wiki page, should I follow this?

Please let me know if there is anything I should be aware of.
