It seems the ASIC chip looks BM1397AG this type of chip is not the same as old ASIC chips this one the top layer can be easily crack or scratch.
I got some images from ASIC manufacturers on Google not the same as the image you link above but I believe they are the same.

I agree with wndsnb you can try it first but for me, it would be better to replace it with a new one. Because the top layer is already damaged and you will only get bad ASIC temp(it will be more problematic) that can affect other ASIC chips.
