the question in the subject title says it all; well, asks it all 
hence the question of 'is there' LoL!Not a good idea. A monitor riser simply sits on top of your desk. Clamping a mount to it will simply cause it to fall over, along with all the monitors attached. If you bolt it down, then maybe but why attach to something weak when you have the desk right there to attach the monitor arms to?
perhaps a wall...but the issue there is behind me in is a corner display full of fine china and wine-ware and that can't be moved, so I have to be a coupe feet away from the wall a there's no space for my chair between the table and chair.I'm sure you can mount something to the desk or wall. What you are asking for is a very rare requirement. You could build something out of 3/4" plywood that fastened to your desk, then mount the arms to that.
hah! those feet are more than the riser!
Considering they are basically scrap flat stock with a pair of holes drilled in them I didn't expect that style of feet to be quite so expensive.
And the table makes more sense as to why permanent mounting isn't an option.
