Well if you don't mind putting holes in the console, what about the top? Here is a VESA mount that is flush with the vertical mounting bar. Notice it has a grommet mounting option. They also have a version with a 4" arm that might give you more options for mounting. The height and angle adjustments can all be tighten down securely to discourage any movements.

I'd consider mounting the screens in a portrait orientation, Then the lower part of the monitor can hang over the top edge of the console, pressing against it to reduce any movement or wiggle when pressing on the screen. The VESA mounts are great but the support is all from the center. It's a little unnerving (at least for me) to have it wobble a bit when pressing something close to the edge. Having it pressed against a key cheek, console bolster, etc. on any side of the monitor really shores it up naturally.
If you are limited on space, consider a portable LCD touch screen. Here is an example:

If you have the right computer hardware, especially a laptop, you'll just need a single USB-C cable that can provide power, data, and video! A conventional TS monitor requires 3 connections. Be sure to examine the specs of your computer you plan to use for HW as not all USB-C port configuraytions can provide video.
