Nope. There is a clear temporary loss of input in many of the manual, but none of the automatic commands. The latter show only "ragged" flanks.

Lionair Upper: manual trim middle: automatic trim

On the ET FDR PF asks PNF to help him with the manual electric trim. So he may have had difficulties actuating his thumb switch.
