Utilizing Eth1 on APX 530/740 as an access port (un-tagged in a VLAN)

I've already read this: https://community.sophos.com/kb/en-us/133199 (APX 530 / APX 740 ETH1 Interface FAQ)

I am not using VLAN 1, it is default and used for STP which AP does not participate in.

VLAN 2 = Corp Network (work stations)

VLAN 3 = Guest

Current Config:

Network Switch PoE+ --> Switchport Trunk VLAN's 2 & 3 --> APX 530 bridged to SSID Corp (VLAN2) & Guest (VLAN3)

I'd like to un-tag Eth1 on VLAN 2 (corp network) and connect a workstation. It is not ideal but I need to recoup the port as this is existing construction and no other low voltage cabling can be installed & the desktop does not do wireless. What I would like this to look like is this:

Network Switch PoE+ --> Switchport Trunk VLAN's 2 & 3 --> APX 530 Bridged to SSID Corp (VLAN2) & Guest (VLAN3) And... Eth1 is Access Port VLAN 2 / un-tagged VLAN 2

Thanks,

Chris

PS. My hunch is the there is no built in SW in the AP and the two Eth Ports are the same, except Eth0 has PoE input.
