 | -------- | ------- | ----- | ---------- |
 | `SKIPGRAVITYONBOOT` | unset | `<unset\|1>` | Use this option to skip updating the Gravity Database when booting up the container.  By default this environment variable is not set so the Gravity Database will be updated when the container starts up.  Setting this environment variable to 1 (or anything) will cause the Gravity Database to not be updated when container starts up.
 | `FTL_CMD` | `no-daemon` | `no-daemon -- <dnsmasq option>` | Customize the options with which dnsmasq gets started. e.g. `no-daemon -- --dns-forward-max 300` to increase max. number of concurrent dns queries on high load setups. |
-| `FTLCONF_[SETTING]` | unset | As per documentation | Customize pihole-FTL.conf with settings described in the <!!!Add Link To New API docs here before release!!!>. Replace `.` with `_`, e.g for `dns.dnssec=true` use `FTLCONF_dns_dnssec: 'true'`

+|`FTLCONF_ENV_ONLY`|unset|`<true\|false>`|If set to true, FTL will use default values for all config values unless explicitly set as an environment variable|
 | `PIHOLE_UID` | `999` | Number | Overrides image's default pihole user id to match a host user id<br/>**IMPORTANT**: id must not already be in use inside the container! |
 | `PIHOLE_GID` | `999` | Number | Overrides image's default pihole group id to match a host group id<br/>**IMPORTANT**: id must not already be in use inside the container!|
 | `DNSMASQ_USER` | unset | `<pihole\|root>` | Allows changing the user that FTLDNS runs as. Default: `pihole`, some systems such as Synology NAS may require you to change this to `root` (See [#963](https://github.com/pi-hole/docker-pi-hole/issues/963)) |
