How to set 4 vlan on the same single ethernet port?

Hi. I own a GL.iNet AXT1800 (Slate AX).

I need to set 4 vlan (tag 10-20-30-40) on a single ethernet port from a switch with tagged traffic, where each vlan traffic will remain isolated and will communicate only with the wan port for internet access, with each one different subnet and different DHCP server for each vlan.
Also… in the vlans 30 and 40 I need to block completely broadcast storm from some aggressive devices.

There is a clear guide for openwrt? I already done this many times with opnsense but with openwrt appear to be completely confusional setup.

Regards.

And you can do it in LuCi as well. Just Google it.
