This code currently shows the option in the GUI. I am not clear how to assign it to the entity. I haven't done it before without a coordinator. More research needed but if someone could point me to an example that would be awesome. I need to essentially set scan_interval = self._config_entry.options[CONF_SCAN_INTERVAL] however the config entry isn't available in the entity.

We do not allow configuration of the scan interval.

We should provide a sane default out of the box. In case the default isn't correct, we should adjust that.

If an user wants to use a different schedule or a conditional scan interval, they can use the homeassistant.update_entity service instead.
