BYOC Edge WebSocket Limits for High Concurrency

Is it possible to bypass the default WebSocket connection limits on BYOC edges when pushing 1k+ concurrent calls via JMeter? We are seeing 403 Forbidden errors on wss://api.mypurecloud.com/api/v2/communications even though our edge capacity is set to 5000. The SDK version is 2.0.150 and we are hitting this wall during the ramp-up phase.
