In order to support BLE coexistence with wifi and improve the capabilities of nina device, BLE communication had to be moved from UART communication over SPI with esp32 vhci feature. This is because some pins of UART and SPI are shared and the coexistence would have been possible only without flow control on UART thus reducing the performance of communication.
