Basics Station Gateway device filtering

I’m using a RAK 7268CV2 in Basics Station operation mode as a gateway to two Vutility Hotdrops. We’re using AWS IoT Core with LoRaWAN with a cell backhaul. I noticed i’m unable to filter devices when using the Basics Station function but am able to connect to the AWS LNS, but when I use Built-In Network server mode in the GW, I’m able to filter devices by EUI but cannot connect to AWS LNS. Can someone either suggest an alternate GW to use Basics Station with that can filter devices, or what I may be doing incorrectly when connecting Built In Network server to AWS?
