How do I specify the algorithm used to solve my model in pyomo?

I want to designate the algorithm used (https://www.gurobi.com/documentation/9.1/refman/method.html#parameter:Method), but I am not sure where I specify this parameter.  I think that it should be included somewhere in these two lines of code:

solver = po.SolverFactory('gurobi')
result = solver.solve(model, tee = True)

All syntax combinations that I have tried have caused errors.

  You can specify solver parameters in the solver object's options dictionary:

  solver.options['Method'] = 1

  This is covered in the Sending Options to the Solver section of the Pyomo documentation.
