Running specific monomer models on alphafold 2.2

Due to the long time required to generate structures of 3000+ residue proteins, I would like to be able to specify running only a specific model, such as model_1 or model_2
In earlier versions of alphafold this was possible with the option "--model_names=model_1,model_2"
I am using alphafold on a machine where I am not root.
I have also tried it on my installation on a machine with a small GPU, where I am running alphafold using docker, and making the following change in the model/config.py file from:
MODEL_PRESETS = {
'monomer': (
'model_1',
'model_2',
'model_3',
'model_4',
'model_5',
),

to:
MODEL_PRESETS = {
'monomer': (
'model_1',
),

still results in all five models being run.
Thanks
Fred
