Nah, they don't have very many mounting solutions available. I tried first using some camera gear / clamps and couldn't get it stuck in the right position, so I ended up using two of these gooseneck mounts: https://www.amazon.com/Tryone-Gooseneck-Tablet-Stand-Compati...

It could be more solid, but the part of the bendy neck closest to the keyboard is resting on the chair's armrest, and that's what gives it most of its stability. These guys[0] put 1/4-20 screw holes on the bottom of their split keyboards, I wish everyone did that.
