Stainless steel pop rivets will NOT drill out easily.
Most likely they will spin in the hole before you can drill through the
head.

If you have access to the back side, a pair of vice grips can solve that.

No access. this plate makes it a captive air tank. Say, do they make a pop
rivet that doesn't leave a hollow behind. No way would i use SS pop
rivets.
