Are these drain holes that need to be uncovered?

Dealer had my 5th gen sent out for a spray in bed liner before purchasing a few months back and just noticed these “bumps” on the base of the driver side of the bed. I know drain holes can get covered/clogged from this process, but couldn’t find a good diagram of all the drain hole locations for the bed. Just want to make sure that’s actually what these are that need to be opened up before I start chiseling away at them.
