How to write a specific reg in ESP32 arduino

Hi I am trying to change the value of this register RTC_CNTL_WIFI_FORCE_PD to force the WiFi to stay down even after a reboot happens. I am using this function WRITE_PERI_REG(0x00020000, 1); but I am getting the following error

Guru Meditation Error of type StoreProhibited occurred on core  1. Exception 
was unhandled.
