Is there any way to swap usb lan eth0 to eth1 and built-in ethernet port to eth0?

Run this from the CLI (copy/paste the whole block) and reboot the device.

cat << "EOF" > /etc/hotplug.d/iface/10-swap_eth_ifaces
[ "$ACTION" == "ifup" -a "$DEVICE" == "eth1" ] || exit 0

eth1mac=$(ip link show dev eth1 | grep link | awk '{print $2}')
	
if [ "$eth1mac" == "b4:a9:fc:04:2b:24" ]; then
	
	ip link set eth0 down
	ip link set eth0 name tmp
	ip link set eth1 down
	ip link set eth1 name eth0
	ip link set eth0 up
	ip link set tmp name eth1
	ip link set eth1 up
	exit 0
else
	exit 0
fi
