Since Yambo v5.1 it is possible to use an algorithm able to accelerate convergences of GW calculations in two-dimensional systems with respect to the k point sampling.
The method is explained in the paper:
Efficient GW calculations in two dimensional materials through a stochastic integration of the screened potential

The method makes use of a truncated Coulomb potential in a slab geometry
