Jetpack TX2

Hi all,
I am working on Jetson TX2 which has the following information:
NVIDIA Jetson TX2
L4T 32.3.1 [ JetPack 4.3 ]
Ubuntu 18.04.3 LTS
Kernel Version: 4.9.140-tegra
CUDA 10.0.326
CUDA Architecture: 6.2
OpenCV version: 4.1.1
OpenCV Cuda: NO
CUDNN: 7.6.3.28
TensorRT: 6.0.1.10
Vision Works: 1.6.0.500n
VPI: 0.1.0
But, I am trying to run darknet on it which requires CUDA 10.2 and also I want to use tensorrt >7. for next application. So, what exactly must I do to upgrade my TX2 ? I searched for some information on forum without clear solution.
Thank you !!!
