OTA reference file missed?

The page reffers to the file below:
However, in the folder by sdkmanager there is no such file at the destination:

/JetPack_4.6_Linux_JETSON_XAVIER_NX_TARGETS/Linux_for_Tegra/tools/ota_tools/version_upgrade$ ls
init                                  nv_ota_log.sh
LICENSE.nv_kernel_bootctrl_generator  nv_ota_preserve_data.sh
nv_kernel_bootctrl_generator          nv_ota_update_rootfs_in_recovery.sh
nv_ota_adjust_app.sh                  nv_ota_update.sh
nv_ota_check_version.sh               nv_ota_validate.sh
nv_ota_common.func                    nv_recovery.sh
nv_ota_decompress_package.sh          ota_make_recovery_img_dtb.sh
nv_ota_exception_handler.sh           recovery_copy_binlist.txt

It took to download the public sources to get the txt file
Image_based_OTA_Examples.txt (47.8 KB)
However, how exactly to create the customized OS thing in the OTA context for default devkit carrier board, but with installed custom software/ drivers, e.g. with installed realsense sdk package?
