One easy solution is to use this $20 12v dimmer driver with 60 watts https://www.amazon.com/dp/B0741VVD6K/
it has a control line that hosts 64 of those dimmer drivers on one bus that can run hundreds of ft without any particular care for shielding etc. Then - that control line ( called DALI ) connects to C4 using this hub https://atxled.wiki.zoho.com/public/Control4-Integration.html
So you have low voltage outdoors, a low voltage addressable control line, and a wired C4 connection for stability. There are a LOT of drivers that work with that same (old) low cost lighting standard and the hub pulls those into the C4 world. 24 volt and 48 volt DC drivers exist too.
