ERA5 hourly data on pressure levels from 1940 to present

I would like to download ERA5 data on pressure levels from 2003-2022. These data will be used to force WRF model over West Africa: Domain (4N - 12N, 18W - 18E). I wrote a python script for that, but when I run it, I am getting the following error message: Exception: the request you have submitted is too large. requesting 5185920 items, limit is 120000. Can anyone helps me?
