How to connect multiple (7-15 devices) BLE peripherals to ESP32 BLE central device?

Hi everyone, need a hand here
When the ESP32 operates as a BLE central device, it can only pair with up to three BLE peripherals and maintain active connections, even though Espressif documentation mentions it can connect to 7–10 devices.
Is there a reason for this limitation? Is there any solution to increase the number of active BLE connections?
Also, is there any ESP32 variant that can pair with 30–50 BLE peripherals and keep all connections active, or any other microcontroller you could recommend that supports this capability?
