I hope you are well today and thank you for your question.
You can try using below solutions to achieve this.
I don’t really want to use a plugin since your theme already supports it. Is there any way I could put the timelines inside tabs?

Yes, the theme also provides timeline but I am not sure whether it fulfills your above-stated requirements.
If it matches with your requirements then you can use it.

Currently, there isn’t any way to achieve this.
The plugins you recommended need payment in order to achieve the feature I want. I simply want them to be grouped into each day of the event, and be able to click the headings to change the timeline shown.
This could be easily achieved with the Tabs component, but sadly I can’t put anything other than text and shortcode inside them. Could you tell me how to work around this?
I don’t know any workaround for it.
If you don’t want to purchase the plugin then you can try achieving it developing custom code.
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
