Right it does that if you have screen unlocked.

If you "forget" them then it should in theory at least keep from creating
PCIe tunnels, so keeping them out of the equation (we just want to
concentrate on the TB/DP side here).

Actually if you use GNOME there is a better way, same dialog but switch off

"Allow direct access to devices such as docks and external GPUs."

this will temporarily stop authorizing PCIe tunnels. You can switch it back
on when you are done reproducing.
