As described in ACF documentation, here is the way to find all posts where a custom field called ‘color’ has a value of ‘red’.
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'post',
'meta_key' => 'color',
'meta_value' => 'red'
));
But in my case, I need to find all posts where the ID of an object post custom field has a certain ID.
How should I proceed to handle meta_value as an object, and targeting its ID key?

Reset to default 1If you use Post Object field type, then it is stored as ID in custom field. So this should do the trick:
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'post',
'meta_key' => '<FIELD_NAME>',
'meta_value' => <POST_ID>
));
PS. You should use 'posts_per_page' instead of 'numberposts' (which is deprecated).
