Ram Upgrade on 2022 MacBook Pro M2 13 Inch

MacBook Pros have not had upgradable RAM since 2012. They got soldered-in RAM when they got Retina screens. Apple kept the 13" 2012 non-Retina MacBook Pro in their new lineup until October 2016, during which time, several of its 13" Retina successors came and went. So in 2016, you could still buy a new 13" MBP with upgradable RAM – but only at the cost of being stuck with an old design.

MacBook Airs and 12" Retina MacBooks had soldered-in RAM from the very start.

No. RAM hasn't been upgradable on MacBook Pros after they were manufactured/purchased since the 2016 models.

RAM and storage (SSDs) are integrated into the logic board and cannot be upgraded. When buying a new Mac, it’s important to ensure you get one with sufficient RAM and storage for your current and anticipated future needs. In many cases, that means buying more than you think you need today.
