Thunderbolt drivers are a FIXED (not optional) part of MacOS, and on a MacBook Pro from 2019, with T2 chip, they can not be removed, and will not benefit from being restored.

What detailed SYMPTOMS are you seeing?

Why do you think Thunderbolt3 Drvers need to be restored?

Thank you! At Network, Other Services no Thunderbolt services, only USB 10/100. I have power at Thunderbolt 1 and a Powlaken multi connected at T2, with an HDMI connected to view an additional display. That display is no longer recognized. At Hardware, Thunderbolt bus says no device connected.

Appreciate advice! I know enough to be dangerous, but not about Thunderbolt.
