Can i get cosine similarity distance in index_factor(IVF1024,PQ32x4fs)

[BangDaeng]

import faiss
import numpy as np
d = 128                      # dimension
nb = 20000000                      # database size
np.random.seed(1234)             # make reproducible
xb = np.random.random((nb, d)).astype('float32')

faiss.normalize_L2(xb)
embed_dim = xb.shape[-1]

index_mode = "IVF1024,PQ32x4fs"
index = faiss.index_factory(embed_dim, index_mode)
index.train(xb)
index.nprobe = 30
index.add(xb)


query = np.random.random((1, d)).astype('float32')
faiss.normalize_L2(query)
distance, index = index.search(query, 100)

in this case i get cosine similarity(0~1) in distance
can i possible?
