Use the SFP+ port on the switch for WAN access.
I succeeded. Created a basic VLAN instead of an interface. Included the SFP port and lan1 in it. Connected the cable from the WAN to lan1, and another from the router's LAN port to lan2 on the switch. Everything appears to function correctly so far. I’m confident it will remain stable.
