Custom Query Categories - AND not OR

I have a modules on a page (e.g. Posts Carousel or Post) and am using the Custom Query option with a category filter. I want to display Posts in the module that contain all of the categories I add, not “any” of the categories that I add to the custom query.

Does anyone have suggestions on either a plugin or other idea that would allow me to, with Beaver Builder, make a module query for example posts that have category a AND category B?

You need to use the fl_builder_loop_query_args filter.
