Jetpack 6 Flashing RT Kernel

I have following question, as this my first time flashing RT-kernel vs working with RTOS enabled controllers, I followed all the steps above in manual on my VM.

To apply the patch, do I first need to,

sudo tar xpf Jetson_Linux_R36.2.0_aarch64.tbz2
cd Linux_for_Tegra/rootfs/
sudo tar xpf …/…/Tegra_Linux_Sample-Root-Filesystem_R36.2.0_aarch64.tbz2
cd …
sudo ./apply_binaries.sh
sudo ./flash.sh --no-flash jetson-agx-orin-devkit nvme0n1p1

Can you please provide the further steps to this puzzle. Is this thread still good to follow
