The meta_value of a post object field is either a Post ID or an array of Post IDs.

If you have the Post ID that you are looking for in that field, then yes. See this page https://www.advancedcustomfields.com/resources/query-posts-custom-fields/ under the array based values section. In this case you would use a LIKE query and search for '"'.$post_id.'"'

if on the other hand you want to do a search that is something like

=> posts your are searching => post object field => some value in the post selected in the post object field

then no, this is not possible. I supposed it would be with an extremely complicated MySQL query, but it is not possible using WP_Query().
