Currently, Calendar interface users can collapse weekends by switching a setting in the timescale:

My suggestion is to have this setting available to creators, enabling them to change the default interface setting:
![theyarelulu_2-1710304349522.png theyarelulu_2-1710304349522.png](/t5/image/serverpage/image-id/33206i6A59D940BB94DD87/image-size/medium?v=v2&px=400)
As you can see, currently this is not possible.
