Remove weekends from a gantt chart

Hi Forum
I was using the forum to try and find a way to remove weekends from a gantt chart, while as I was looking I noticed one that was way better than the one I had made but it also has weekends. Wondering if anyone would know how to make a gantt calendar only show Mon-Fri as I want to use it to build a production schedule and it splits the demand over 7 rather than 5 days.

Please see attached, any help greatly appreciated.
