Possible to replicate this MT7530 VLAN config on RTL8366S?

It's nice that the default VLAN config for a MT7530 switch puts LAN and WAN on separate VLANs. Is it possible to accomplish the same on RTL8366S, given it doesn't have a dedicated "WAN" port as seen in the Switch config?

I have the same question but with the Linksys RE6500. I tried to make changes to the "switch" and it won't save the settings.
