Default Lid driven cavity case for non-Newtonian fluid

Sheetal Airan is on a distinguished road
I am trying to stimulate the lid driven cavity case for non-Newtonian fluid. For Newtonian case, I had validated the results at Reynold number Re=100, 400.
For Newtonian case, in transport properties, we set kinemetic viscosity, nu which can be calculated by this equation: Re=UL/nu
where U is the characteristic velocity, L is the characteristic length.
So, nu=UL/Re.
If U=1, L=1 and Re=100 then nu=0.01 and for Re=400, nu=0.0025

But in non-Newtonian case, we select the model like power law or Herschel-Bulkley model and set the parameters of model in transport properties instead of giving nu value.
Now, I want to simulate the non-Newtonian case for different Re values but I am not getting how to change the Reynold number as we cannot set the nu value in the non-Newtonian case.

Any suggestions or help will be appreciated.
