ESP32 Wifi Limited to 4 devices?

I have 3 ESP32 devices running WLED, one RaspberryPIZero, one control device to managed the UI (mobile phone). There is no home network/wifi so one of the ESP32’s act’s as the Network Access Point and the other devices connect to it.

Normally an ESP32 is limited to 10 devices with a default setting of 4. Is there anyway to adjust/change the default limit in wled? Documentation is at Wi-Fi - ESP32 - — ESP-IDF Programming Guide latest documentation
