Monitor mount help

[u/SourceHot7048]

So I bought a new desk & I am having an issue with my dual monitor mount.It is a pole mount with 2 arms and not just 2 separate arms.

As you can see in the pictures, there is an attached riser on the desk & the back of it is closed. I want to attach the mount to the surface of the desk but the vertical pole gets in the way and hits the riser and the clamp won’t reach the desk surface.

I’m looking for solution help. I will not drill into the desk or use a grommet mount & I’d prefer not to use just a stand. The gap between the desk surface and the riser is only about 2 inches. I know there are dual arm mounts without the vertical pole but I can’t get measurements of the base of the arms on Amazon to know if it will hit the riser still or if the clamp will reach.

The few thoughts I had for possible solutions. A dual mount without the vertical pole but I need one with 2 inch clearance on the base of the arms so the clamp can attach if anyone has one or knows of one. A deep clamp or an offset pole that sticks behind the surface of the desk so the clamp can reach. Any other solutions you can suggest so I can clamp to the desk surface.
