Question about multiple NIC and Load balancing traffic

[sgnsys3]

Is LibreQos support multiple incoming and outgoing NIC?

Network Diagram

I have read this document https://libreqos.readthedocs.io/en/latest/docs/Quickstart/configuration.html
My understanding I have to config lqosd.conf like this

[bridge]
use_xdp_bridge = true
interface_mapping = [
       { name = "eth0", redirect_to = "eth2", scan_vlans = false },
       { name = "eth2", redirect_to = "eth0", scan_vlans = false },
       { name = "eth1", redirect_to = "eth3", scan_vlans = false },
       { name = "eth3", redirect_to = "eth1", scan_vlans = false }
]

Will QOS still work when traffic balancing over on edge-1 and edge-2?

Thanks
