<?php 
  
  new my_pluging_name_acf_group_save();
  
  class my_pluging_name_acf_group_save {
    
    // list of field group IDs used in my plugin
    private $groups = array(
      'group_5cd98d69d9edd',
      'group_5cdd8ef037a51',
      'group_5cdda2c94c13a',
      'group_5ce3e785e644e',
      'group_5d41e7d89ed6c'
    );
    
    public function __construct() {
      // add fitler before acf saves a group
      add_action('acf/update_field_group', array($this, 'update_field_group'), 1, 1);
    } // end public function __construct
    
    public function update_field_group($group) {
      // called when ACF save the field group to the DB
      if (in_array($group['key'], $this->groups)) {
        // if it is one of my groups then add a filter on the save location
        // high priority to make sure it is not overrridded, I hope
        add_filter('acf/settings/save_json',  array($this, 'override_location'), 9999);
      }
      return $group;
    } // end public function update_field_group
    
    public function override_location($path) {
      // remove this filter so it will not effect other goups
      remove_filter('acf/settings/save_json',  array($this, 'override_location'), 9999);
      // override save path
      $path = dirname(plugin_dir_path(__FILE__)).'/acf-json';
      return $path;
    } // end public function override_json_location
    
  } // end class my_pluging_name_acf_group_save
  

There is also a plugin https://github.com/khromov/acf-local-json-manager

and I’m sure there are other filters available
