How to use pcie overlay dtbo file

Hi, nvteam,

we are debuging the pcie c5. we find the status property of pcie_ep@141a0000 and pcie@141a0000 are overwrite by the setting in file tegra234-p3737-overlay-pcie.dts.

when I want to change the status, replace kernel_tegra234-p3701-0004-p3737-0000.dtb in directory /boot/dtb/ and tegra234-p3737-overlay-cpie.dtbo in /boot/ has no effect.

Now everytime i want to change the status. I have to reflash the whole orin with cmd sudo ./flash.sh -r jetson-agx-orin-devkit mmcblk0p1 so I wonder if there are a simple method to realize the purpose of modifying status
