USB C using laptop power while its off

[JYGael]

I have an ASUS ROG STIRX G18.
The problem I have is that the USB C port consumes power when the PC is off.
In the bios it only lets me activate or deactivate the ERP but it doesn't let me choose whether to use s4 or s5.
I already tried activating the ERP and I had no solution.
The same thing happens with the ERP deactivated.
I have a USB monitor and I want it to not consume energy when I turn off the laptop.

I'm worried about it draining the battery.
