[SOLVED] Extra mobo screw hole?

[SaltLight]

Hi, I recently bought the Gigabyte z390 gaming x mobo. It has 7 holes for standoffs but only 6 actually fit my case, which supports itx all the way up to eatx. The hole is just under the ram and to the right very slightly. Does anyone know what this is? Thanks

Just another hole, of same use as the others to accommodate some other backplates.
