I looked at my soundbar to see what was there. But I didn't find any holes to hack into or anything like that, except for 2x M6 threaded holes. Maybe you can tinker with it yourself👍🏽.

The soundbar has no screw holes on the back, only the 2xM6 holes mentioned on the underside. Something would have to be done with wall anchors that end in a flat bar so that the SB can be placed on top and screwed on from below - not very attractive to look at...
