How to use dev-branch quirks

i want to use hue dimmer switch v2. The needed quirk was just added to zha-device-handlers dev-branch:

But i have no idea how to get the new quirk into my installation!

I tried installting the “Custom deps deployment” addon with configuration zha-quirks=dev but log says "ERROR: Could not find a version that satisfies the requirement zha-quirks==dev"

Is there a way to copy the new file(s) ? I couldn’t find a “zhaquirks” directory via busy-box/ssh find command.

Please give me a hint. Thanks!
