Filter outlier for frontend/registry entity

Hi there,
I configured a couple of SwitchBot Indoor/Outdoor meter using the HA front end, but there are some glitches in the temperature that I would like to remove, for example by filtering outlier. I know there’s the filter platform that would do that. However, as the entity is configured using the front end, there’s no configuration.yaml file for that, AFAICT, it’s all in a registry.
Is there another way to configure filters?
