I'm not aware of a program that is available publicly that would do this already, but such methods have definitely been implemented. You could, for example, take a look at some of the papers by Angelo Frisani on this. So the question is what you mean by "out of the box". It's possible, but it'll require work like any other advanced numerical method.

[deal.II] Lagrange multipliers
Hello all. I am very new to the community but very eager to learn. I am wonder if there is an out-of-the-box support for using Lagrange multipliers on a boundary, to enforce rigid body motion in Stokes flow, similar to the work of Glowinski [1] or Hwang [2]?
