Enable (or disable; it is true

as well as applying nonlinear residual and Jacobian terms based on constraint equations.
This is probably only safe to disable if user code is setting nonlinear residual and Jacobian terms based on constraint equations at an element-by-element level, by combining the asymmetric_constraint_rows
option with the residual_constrain_element_vector
processing option in DofMap
