When you use the bracer of flying daggers, you aren't drawing weapons to attack with. You're activating a magic item, and the time it takes to use it is specified by the item. For example, jump normally takes an action. But a ring of jumping lets you cast the spell, targeting only yourself, as a bonus action.
So, no, it's not possible to use the bracer as a bonus action. They'll have to draw and throw an actual weapon. But they could use it with their Action Surge.
A Battle Master's Quick Toss maneuver allows you to draw and throw a weapon as a bonus action instead of a full action.
Bracer of Flying Daggers allows the user to draw up to two daggers and throw them as an action.
Can a Battle Master legally use Quick Toss to use the Bracer as a bonus action, or no?
