How to install tensorrt version 6.x on jetpack 4.5

Hi all,
I need tensorrt version 6.x for my project.
the current jetpack on my Jetson is including tensorrt version 7.
do we have any method to roll back the version of tensorrt ?

thanks a lot.

No, there are dependency at low layer drivers, thus can’t just roll back the TensorRT, you need to reflash to old JetPack which provides TensorRT6.x.
