The Display On My Macbook 13 Pro With Two Thunderbolt Ports Is Loose Macbook Pro 13 Two Thunderbolt Ports Late 2020

Chosen Solution

The newer MacBook Pro’s fro 2016 onwards use a press-fit pin into the lid assembly as you can see here

So you can’t tighten the lid side, only the body side which is anchored with three screws per side. I would take your system to an Apple Store or authorized dealer to have them replace the display assembly if your system is still under warranty. Sorry the M1/M2 systems all have soldered RAM and Storage (Flash) as you can see here. No means to upgrade either.
