Now, it seems latest handshame must > 135 s to be sure that tunnel is down, how can we specify a small delay, as 30s for example. Regards, Nicolas Prochazka.

This isn't negotiable. However, I'll at some point be adding netlink event notifications, so that you learn when WireGuard itself has detected connectivity problems (usually in about 15 seconds), and react accordingly.
