Burying Govee Wires

Recently purchased the new Pathway Lights 2 Lite. The wires are directly connect to each light stick (4 sticks spaced about 4 feet apart). Curious if anyone has thoughts on how to go about properly burying the wires. I’m thinking split flex tubing night vent only option given I can’t slide the wires through closed tubing. I don’t want the wires to degrade after a few years.
