Hi,  
You should be missing some steps in  
[Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation](https://docs.nvidia.com/jetson/archives/r36.4/DeveloperGuide/SD/Kernel/KernelCustomization.html#building-the-nvidia-out-of-tree-modules)

After the step:

> 1. Run the following commands to install:
> 
> ```auto
> $ export INSTALL_MOD_PATH=<install-path>/Linux_for_Tegra/rootfs/
> $ sudo -E make modules_install
> 
> ```

The 3 files will be copied to

```auto
<install-path>/Linux_for_Tegra/rootfs/usr/lib/modules/5.15.148-tegra/updates/

```
