Precision 7760 3-button Touchpad

I just set up a brand new high dollar Precision 7760 Workstation. Great potential performer. M.2 2280 512 GB, Gen 4 PCIe x4 NVMe, Solid State Drive; 16 GB, 2 x 8 GB, DDR4, 3200MHz , Non-ECC, SODIMM; 11th Gen Intel Core Processor i7-11800H (8 Core, 24MB Cache, 2.30GHz to 4.60GHz, 45W).

You know what it doesn't have? It doesn't have a way to disable or reconfigure the center button on the 3-button touchpad.

So far, I have been unable to find out who manufactures this part, who makes the driver, etc.

Not disabling this button can lead to accidental closing of browser tabs and undesirable scroll lock behavior.
