Force Scroll in Flexible Layout

Does anyone know if it is possible to keep UX from resizing widgets when you are in Flexible Layout mode? We have a dashboard that was built on a large monitor which is what users use about 50% of the time. The other 50% users are on their laptops without an external monitor. When this happens UX resizes all the widgets to fit on the screen, which makes none of them readable. Is there a way to use Flexible layout, but also lock the widget size so that on smaller monitors scroll bars are used.

Maybe there is a way to add another “device” so that a resolution greater than X is a flexible grid
