Honestly, I don’t know, I did a for acf bulk edit and it came up. The plugin is for the quick edit. I assume this means that if you’re on the posts list page in the admin and clicked the “Quick Edit” link.
There have been many requests here for a bulk editor for ACF fields. There is not a solution for bulk editing ACF fields that I’m aware of.
This plugin also provides support for ACF fields https://www.admincolumns.com/features/
