I like to have steam notifications enabled but as far as I can see, Bottom Right is the only option under the new Steam client. This gets in the way if using other programs which make use of this area on screen.

Previously, the Skins feature could be used to get around this.

Attempting to modify this in the Steam\resource\styles\steam.styles triggers an integrity violation and a redownload of the steam client.

So for Steam users, the only option for now, is to disable notifications entirely.

Please add functionality in Settings -> Notifications to set window position, like is possible in CS2.
