None that i'm aware of. But since you only mention those 2 member (rather than all 5 members who gave you negative feedback), theoretically you can ask DT member to exclude those 2 members from DT system. But i doubt it'll happen.
I think OP is considering possible DT member's feedback. I looked at his feedback received history. Lauda and JollyGood seems two users who can be in the DT list considering their history. Possibility for others are very little unless some of them start actively contributing to the reputation system and in the future their feedback starts showing up as trusted feedback.
Everyone forgot about Lauda because he left the forum but JollyGood is still active and according to my study few months ago I found most of the negative feedback left by him are out of harsh judgement or retaliation. He even leveraged his DT power not to pay a user for the work that user has done for him instead he left a negative feedback to that user to stop his mouth. Eventually the user left the forum.
