Vlan on Wan Port

So I’m setting this thing up for the first time (Dual Gigabit Ethernet Carrier Board for Raspberry Pi CM4), I have the latest image of OpenWRT Installed (21.02) and I’m having a bugger of a time finding the vlan options within this thing, I will mention I am new to OpenWRT, and after looking online for this answer, none of the solutions appear to be available in this build. All I need to to in order to deploy this thing is setup a vlan on my wan port, does anyone have some insight on this?
