Nothing else to say. Unlike other BOFFs (for example, 23c), this store-bought BOFF which brings the Discovery away team vest with it, is non-customisable when it comes to the uniform and head options. It's only option is the Discovery era uniform and no way to change it in my brief testing.
On the plus side, the away team vest is a "chest gear" item and can be worn over any kind of uniform which is nice
