How to disable "Enable hardware MPI (bignum) acceleration" using arduino as framework and esp32 as platform and platformio ide

I am using ESP32 DEV MODULE KIT for esp32 and I want disable “Enable hardware MPI (bignum) acceleration” using Arduino framework, can someone please help me out?

Where exactly do you see that this option is enabled? Searching for bignum only reveals the mbedTLS code (enabled via vMBEDTLS_BIGNUM_C) and SDK-internal stuff for WPA2 bignums.
