The switch model is actually an SG2008 and the hardware version is v4.20.

In the release note for the latest firmware, under new features it states "Added support for Private VLAN".  Is any guidance available for setting up a private VLAN?  The information found on the internet states "The Private VLAN (PVLAN) feature in TP-Link Omada is a networking security function that provides Layer 2 isolation between devices within the same VLAN."  This is interesting and I would like to test it further but I see no new settings in the existing controller.
