Depend on what you want to do with a "partial step". If it is
to refine an existing layout, then the answer is no. Since layout
with GraphPlot is very cheap anyway, you could just let GraphPlot
do a complete layout. If you want to see how the algorithm work
step by step, then you can use MaxIterations or Tolerance to
control how many iterations you want GraphPlot to perform. e.g.,

GraphPlot[g,Method->{SpringElectricalModel,MaxIterations->1}]
