You want [Deprecated]Govee Integration for Govee Light, Switches, Plug, and now Appliances for any Govee integration. @mavrrick58 created and maintains it and you can find information about their Christmas Lights in the thread including how to control the via LAN in Hubitat.
As for Twinkly, it is not integrated into Hubitat. If you have a version that integrates with HomeKit, you can use virtual switches to gain some control.
For Nanoleaf, they can be controlled via Matter. So, if you have a C8 and our in the beta program, you could connect them directly to Hubitat. Otherwise, it would be using virtual switches like Twinkly.
