(I know that use of thrust levers is not very probable, but anyway).
I don't understand what you are referring to.
The aircraft uses multiple sensors to ascertain "on the ground" status.
TCMA does not affect the thrust levers. It closes the high pressure shutoff valve (HPSOV) when it (1) detects UHT (2) on the ground.
You can find more details in the patent linked in post #9.
