I don’t know of any video. The steps are not difficult.

You create an acf/save_post filter https://www.advancedcustomfields.com/resources/acf-save_post/

In this filter you get the value of the true/false field and then you can use update_field() https://www.advancedcustomfields.com/resources/update_field/ to change the value of the other field based on what the true/false field value is.
