Downgrade tensorrt10 to tensorrt8.6 in jetpack6.2

Hi, I have a jetson orin nano on which I have installed jetpack6.2 and tensorrt10 is installed by default on this jetpack. Now if I want to use tensorrt8.6 version instead of version 10 and install it, what should I do? Please guide me in this regard.
Thanks

Dear @jack_calla ,
You can’t upgrade/downgrade TRT. You need to install the corresponding jetpack release.

thanks.
