How to extract conventional standard type CIF files from Materials Project through pymatgen or matminer

Question

I use Matminer to get CIF file from Materials Project.The code is:

from matminer.data_retrieval.retrieve_MP import MPDataRetrieval  
mpdr = MPDataRetrieval(api_key='My_key')  
df = mpdr.get_dataframe(criteria='Mg2SiO4', properties=['cif'])

The CIF file I extracted from the above code is displayed on the webpage of the MP database as 'Cumputed'. Its structure in VESTA is shown in the following figure figure 1figure 2

But I see that this is a 'Conventional Standard' type CIF file on the MP database website. What I want to extract is this type of CIF file figure 3figure 4

So I wonder if there is a way to directly extract 'Conventional Standard' type CIF files, either with Matminer or with Pymatgen.Or is there any way to convert a CIF file of type 'Cumputed' into a CIF file of type 'Conventional Standard'.
