Summary: You may encounter a Dell Command | Power Manager (DCPM) warning for an unsupported Thunderbolt 3 device message after an upgrade to the latest BIOS for your system.
When you download the latest Dell Command | Power Manager 2.2.1 (or newer) and install it along with the latest system BIOS, below message will appear when the Dell Business Thunderbolt Dock (TB16) is attached to a non-Thunderbolt 3 enabled system. (Figure 1.)

This is working as expected.
After installing Dell Command | Power Manager version 2.2.1 (and newer) along with the most current system BIOS you will receive compatibility notifications due to the incompatible USB Type-C device being connected to the USB Type-C port of the system. (In this case a device that requires a Thunderbolt 3 controller.)
