How to activate Wireguard login "wireguard +p"?

In normal Linux for activating logging of Wireguard you have to activate it that way:

sudo modprobe wireguard
echo module wireguard +p | sudo tee /sys/kernel/debug/dynamic_debug/control

but in OpenWRT the directory dynamic_debug does not exist.

Is there any other way to activate logging for Wireguard?
