# Customize the Sandbox Network Policy: Details ## Remove a Custom Preset Custom presets applied with `--from-file` or `--from-dir` are recorded in the NemoClaw sandbox registry alongside their full YAML content, so they can be removed by name — the original file does not need to be kept on disk: ```console $ nemoclaw my-assistant policy-remove my-internal-api --yes ``` `policy-remove` accepts both built-in and custom preset names. Run `nemoclaw policy-list` to see every preset currently applied to the sandbox.
