OMR on RPi 4b using LAN switch instead of USB LAN adapters for line bonding

[L1TTL3big]

I'm currently using OMR on RPI 4b in such a way that LTE/5G modems are connected to RPi via USB(3.0) LAN adapters and another router (yeah might be strange but LAN setup is inherited before I was aware of OMR - the whole network was already set up and I'm not keen to reassemble it) is connected to RPi LAN port. Somehow I ended up using one of such USB LAN adapters on some of my PCs and I've noticed they're actually decreasing latency/speed opposed to "classical" LAN cards. Therefore I'd like to know if it would be possible to attach both LTE/5G modems and router on LAN switch (which can be configured to work as both managed and unmanaged switch) and then connect switch to RPi LAN port instead of using USB ports. I'm quite sure this way I would gain some latency improvement over using USB LAN adapters. I'm LAN basics aware but I'd like to know if (i.e. #2003) this setup would work and if someone could provide me some basic instructions how to implement it. I guess by just connecting everything to switch and then switch to RPi wouldn't work out of the box ...
Thank you - much appreciated.
