Yes, there is a way. Say you wish to remove the "Confident Commander" trait. That is level one of the GoodCommander trait line. To remove it, you will need to enter this:

give_trait "Character Name" GoodCommander 0

Similarly for Fiscally Flexible, which is level 2 of the Embezzler trait line:

give_trait "Character Name" Embezzler 0

You can find info of the trait lines and levels in the RTW/data/export_descr_character_traits.txt file, as well as in the trait guides listed in the Colosseum Forum Index.
