NVIDIA 4.9.190 Tegra Ubuntu Kernel

Hello, I use Jetson Xavier boards with ubuntu 18.04 and 4.9.190 Tegra Kernel. I have Kubernetes running and docker containers which has deep learning applications. Now i want to place checkpoint of the docker containers. I use checkpoint tool (CRIU) but inorder to use the tool it needs Kernel support(Few features in the kernel configurations has to be enabled (Linux kernel - CRIU )). When i try to enable features in the .config file and run the make file it throws errors.

Is it advisible to modify the kernel configuration file.? Am i on the right way?

Config file path : /usr/src/linux-headers-4.9.140-tegra-ubuntu18.04_aarch64/kernel-4.9/.config
