That is not possible with authorization. It is possible to authenticate using a passkey, but not authorize. Maybe you could build this into the application? You could use one characteristic for the passkey, then the peripheral can check it, and only send notifications to the central when it is correct?

Thanks. But is there a way to set a password there, which will be coming from the GATT client that want to read from/write to the specific characteristics?

Please examine this MSC.

You need to handle the BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST event, and respond with sd_ble_gatts_rw_authorize_reply(SUCCESS) or sd_ble_gatts_rw_authorize_reply(WRITE_NOT_PERMITTED)
