If you have space behind your desk, then any of the arms mentioned in this thread will work. You can have the majority of the arm bent back kind of thing. If you don't have that space, something like this would work.
Hey I couldn’t find the exact one I purchased but found the similar on amazon!

I prefer the post mount style of monitor mount. I find them more stable and less wobbly than the gas piston or spring arm mounts. I also prefer one mount per monitor but dual monitor mounts do exist in the post mount style.
OP's post is unclear if they did try a VESA mount. In which case, depending on their desk setup, I'd recommend either a post or arm on post mount to solve their issue. After having quite a few monitor arm solutions between work and home, these are by far and away my top recommendations.
I went through this, you will want 3.
I have a curved ultra wide and two curved 27” monitors.

I used a less mobile one for the center,to push the monitor as car away as possible:
