Mostly, yes. In VR, it's just a matter of positioning the UI closer to you. If you are in Desktop Mode, the vamX UI can also be moved closer to you. Press the Detach button in the vamX UI. The move around to position the UI as you want, then click Attach to fix it in place. If you are in Desktop Mode and the non-vamX UI is too small, that can't be easily changed, but is probably because you are on a small 4k screen, and therefore the UI is a bit small. In this case I wonder if you can do something in Windows, definitely you could decrease the resolution of that screen before launching VaMX, and that would increase the menu size.
