In theory, it should still work. That is usually used for grounding purposes on laptop motherboards, but most motherboards have multiple redundant ground paths.

Worst case scenario... Solder a jumper wire on if it doesn't work.

I tested it and yes it still work,
Also i see another grounding component like this, so this motherboard have two grounding in the back

But it still safe to use only one grounding?
