Make a tcolorbox table, using tabularx, fit the linewidth

I have a pretty formatted table with tcolorbox, which uses tabularx under the hood. But, I don’t know how I would configure it, as is possible with tabularx, to make the table fit the linewidth – without leaving a blankspace inside the table.

One solution I would be looking forward to have would, for an example, stretch automatically one of the cells to make it occupy the total space (like what my goal-table does with the "Esteira Transportadora" cell).

I’m reproducing this table:

Currently looking like this:
