Can LoRa Gateway Block specified LoRa nodes

Hello,
I have a raspberry pi based gateway and few nodes. Say I have 2 gateway and 50 nodes. Is it possible to configure the one gateway to accept signals from first 25 nodes and reject other 25 and similar for the second gateway accept signals from other 25 and reject first 25. Thank you.

No that’s not possible, gateways receive all nodes within reach and forward data
