Can I do a DIRECT CONSULAR FILING OF I-130 at US emby Bahrain?

Does anybody know if the US Emby in Manama, Bahrain does this DCF (Direct Consular Filing)? I called their direct line and they just kept on directing me to operator line which says I have to go to travel.state.gov or USCIS website. I heard DCF saves more time and expedites the visa processing. I really need an information about this. Thanks
