Hello @danie_ditz,
Thank you for writing to us.
You can setup two custom links on your site menu. Each with different links to your events page. One link can have ?events_view=month at the end of it, like this: https://sicorn.ca/events/?events_view=month. And the other can have ?events_view=list, like this: https://sicorn.ca/events/?events_view=list. Both links will open the same events page but with different views applied.
Also, we will be adding views attribute to the events shortcode soon in a future version update.
