There is nothing in ACF that will let you add a field group in that location. All ACF field groups need to be associated with a single WP “Object” (post, term, user, options page).
Also, WP does not offer any hooks to modify this page.
There may be a way to do this using JS https://solarisedesign.com/blog/adding-content-above-and-below-the-wordpress-admin-posts-table
And it might be possible to use acf_form() to add a custom form there, possibly saved as options. But, to be honest, I’m not sure that would work.
