Developer options, 'activate terminal' and when rooted you can switch to root with su. That is an alternative when you use 'adb shell' to get rid of the bloatware.
I'm using Titanium Backup (for more then 10y now) on my rooted/custom rom to freeze or uninstall system apps (so I don't know any other method). Main use of the app is full backups though, including apk. (so I had it registered with a license file purchased, so I can use it even on devices without google store)
You can use LADB, but it is not free unless you compile the app yourself.
You can use Bugjaeger instead, which can achieve the same thing (just a bit trickier to use). It is free on the Play Store but has ads. You can use an ad blocker in the background though, it's not a big problem.
Not completely sure about this but maybe termux can do this, but I think you still need access to a PC.
