I don't think you can fix a hole in your motherboard, only thing you can do is replace it with the same model.
I once took my laptop to a shop to change my charging port, and I told them I wanted to do it myself, but I didn't have a soldering iron.
They told me: If you want to solder on your motherboard, you have to be careful and have previous experiences with soldering, soldering on motherboards is a really fragile job, you heat it too much and you go through the layers of the motherboard.
From that day, I have not tried soldering on the motherboard, because I am living on a tight budget.
