PC + USB cable + ADB ()
Device, Settings, Developer mode ON (search the internet)`
Connect PC to device, command line:
adb devices
adb pm uninstall --user 0 applicationID
applicationID? Some tools like NetGuard will show you this.
Careful what you uninstall, run adb shell cmd package install-existing applicationID to reinstall.
Notice that uninstall above just does it for CURRENT USER, it’s not like when you have root, a system update or restore, will bring them back.
As usual a search for “xda devicename debloat” helps you find out what you can safely uninstall.
