Edge is built into Windows 10 / 11 and even more so that now deprecated Internet Explorer.
It cannot be Natively removed and you cannot Natively disable the functionality.
Remove any shortcuts to Edge and then set your own Browser (e.g. Chrome) as Default Browser. You can do this and Edge will not be intrusive. It may come up once in a while.
Go to Settings, Apps, scroll down to Edge and do a Repair. This will fix any issues Edge is having.
There is now not much to choose from between Chromium Chrome and Chromium Edge.
