I’m not sure about cans but I doubt it as I stated before, nitrogen basically can’t dissolve into water. I know guinness is typically forced through restrictor plate which uses beer gas (25% Nitrogen 75% CO2) for the extra pressure needed.
That massive head is all the nitrogen leaving solution
Guinness is charged with nitrogen and CO2
