DRL in Yaris from..?

So, disconnecting that signal should fool the DRL module into thinking that it should not turn the DRLs on.

Yes, there is yellow between two greens. I was surprised because all lights stopped working when I unplugged the DRL. If I cut that wire tail lights as well as headlights still working when I manually turn on the lights? Right?

I believe so. To be safe, either pop the pin out of the connector, or cut the wire with enough left on the connector side to be able to reconnect if that doesn't work.
