Is there a way to disable iOS homekit notifications when using homebridge?

It seems like it’s mirroring my HA notifications so I get an IOs one and an HA one.

I think you can shut off any notification / banners / lock screen on an iphone from the settings on a app specific basis.

In the Home app long or 3d press on an accessory then select Details. You can set the Status and Notifications, name, icon, whether to include in Favorites, and grouping with other accessories.
