Question Motherboard white line

I have a Gigabyte b450 gaming X and I was wondering what could be this white line around one of the holes for stand offs near the ram ? ( yeah the hole is not in use beacuse my case does not have a space for that one specific hole)
A guess is it's a drizzle of white ink from the silkscreen process that puts markings on the PWB. Insignificant.
