I tried two times and it’s a bit fiddly but it works.
Once you pried a slot between cover and unit (worked best with a plectrum in my case) on all sides except the inside of the battery slot, a little bit of wiggling left and right, back and forth and the cover came lose with near no force.
Edit to the post:
I had a oem 256gb ssd manufactured by Samsung installed by default, so I think they’re swapping parts sometimes.
Also I was really afraid of breaking the 2mm diameter round sata cable.

Its disassembly method is very simple, just like the ThinkPad T470, you only need to remove the external battery first, and then remove all the screws on the bottom case. Use the guitar pick open the bottom case slowly, and there are many snaps on the back cover to securing the case to the laptop body, be careful do not break the snaps.

Update
Another version of ThinkPad T480 has an M.2 2280 SSD and installed via an adapter. Please see the ThinkPad T480 review here.
I’m falling back to options for the T480 because of this year’s disaster of a design T490.
On Lenovo web site, I see T480 with two separate drive slots
1. traditional 2.5″ slot for magnetic hard disk or M.2 2280 SSD.
2. M.2 2242 SSD.
How would I know, if I first buy it with a traditional disk, then replace it later with a M.2 2280 drive, that the adapter cable will be there? Or do I have to source for that cable component separately?
