Maintaining two tensorRT installations on jetson TX2


I would like to upgrade some older software I wrote on my TX2. It was implemented using tensorflow 1.13 and tensorrt 5.0.
I have flashed the jetson with jetpack 4.3 to have the lastest stable release of everything. Now I am setting up a virtualenv in python with tensorflow 1.13 but also want to install tensorrt 5.0. Can I manualy install a second tensorrt version to use in a virtualenv?

I do not seem to find installation instructions for jetson other than use jetpack. I need the virtualenv with older versions as a fallback option. Thanks
