My computer needs a bios/uefi update but I can't find it.

My mother board is an Intel H511-VD4. Problem is that it's not made by Intel, it's a generic made by a chinese company named Huananzhi. I can't access their website to get the bios update so I'm coming here in hopes anyone knows another website or forum where you can find bios updates just in case I can find my motherboard's there.
