I know how to remove it but ATM that involves removing all of CBS (Component-Based Servicing) and that includes TextInputHost (on screen touch keyboard) and ScreenClipping (UWP version of the snipping tool) so removing it would break those.
It's easier to remove SystemApps than it used to be but it involves registry edits (basically you end of life the app so it can be removed with remove-appxpackage) so it's not something I'd recommend doing unless you're confident in how to reverse things.
If you're interested
this gist gives all the details of how to EOL SystemApps if, like me, you're interested in learning through doing. I'm working on a good way to catch and prevent Edge update from downloading Edge after a Windows update so once I'm happy with that I'll start digging into Windows Back Up so if i discover a easy/clean way of removing that I'll let you know.
