In Eikon, I can use the "block trades viewer" to access block trades historical data. I can also in excel get the info for the last (only the last one) traded block trade (=TR("NOOZ8","BLK_DATE;BLK_PRC1;BLKTRDVOL;BLKVOLUM;BLKTIM_MS;BLKCOUNT","CH=Fd RH=IN") ). I can do it in python too. However, I cannot get the historical data in python/or excel.
