networks_pre_query

Return a non-null value to bypass WordPress' default network queries. The expected return type from this filter depends on the value passed in the request query vars: - When $this->query_vars['count'] is set, the filter should return the network count as an integer. - When 'ids' === $this->query_vars['fields'], the filter should return an array of network IDs. - Otherwise the filter should return an array of WP_Network objects. Note that if the filter returns an array of network data, it will be assigned to the networks property of the current WP_Network_Query instance. Filtering functions that require pagination information are encouraged to set the found_networks and max_num_pages properties of the WP_Network_Query object, passed to the filter by reference. If WP_Network_Query does not perform a database query, it will not have enough information to generate these values itself.
