 | `proxy` |   |If `mode` is set to `system` instead of `manual`, Docker Desktop gets the proxy values from the system and ignores and values set for `http`, `https` and `exclude`. Change `mode` to `manual` to manually configure proxy servers. If the proxy port is custom, specify it in the `http` or `https` property, for example `"https": "http://myotherproxy.com:4321"`. The `exclude` property specifies a comma-separated list of hosts and domains to bypass the proxy. |
-| `enhancedContainerIsolation`  |  | If `value` is set to true, Docker Desktop runs all containers as unprivileged, via the Linux user-namespace, prevents them from modifying sensitive configurations inside the Docker Desktop VM, and uses other advanced techniques to isolate them.

If it is set to 0, a random free port is chosen. If the value is greather than 0, use that exact value for the port. The default value is -1 which disables the option. Note: This is available for Windows containers only. |
