There are brews which are Tunnel or Flash Pasteurized commercially but as previous statements identify, it is not necessary for the majority of beer.
I was just reading about a particular Scottish ale that has a hefty amount of processes... including flash pasteurization. These ales have residual sugar as they halt fermentation a little early, I think they simply wanted to extend shelf life and not have bottle bombs.
If I ever had the inclination I would put bottles or cans in the boil kettle and
fill with hot water for 132-140F, wait a short time and chill as fast as I could. Do not direct-fire the kettle with your goods in it, use pre-heated water.

I would absolutely LOVE to check out Coors yeast vault and lab
Funny story regarding Coors... we sold them some (non-brewing) process equipment years ago, it had a large 460V electric heater with hermetically sealed mercury contactor (we use them because they FAIL OPEN, if they ever fail). They threw a tantrum!!! They replaced with AB mechanical contactor whilst shaking their finger at us, I told them that is OK but replace it every 2 years due to the severe cyclic rate. Fast-Forward 8-10 years the brewery had a fire because the contactor fused CLOSED. After I confirmed nobody was harmed I laughed to myself while they ate humble pie.
I should have asked what color their Cold Activated cans turned that day
