Dest, 23, assisted Antonee Robinson's opening goal before being sent off in the 39th minute.
Trinidad levelled minutes later, with Alvin Jones giving them the lead in the 57th minute.
Berhalter said he does not want this situation to become a "witch hunt" and that Dest had apologised to the team.
He's going to learn, he's going to grow.
"It's something I have to learn from and it won't happen again!," Dest said.
