Is ESP32 WIFI NVS FLASH needed or not?

[samsonch]

My application alwasy loads WIFI configurations for every bootup, like:

COUNTRY_POLICY
WIFI_MODE_STA
ESP_IF_WIFI_STA
WIFI_PS_NONE

I did not use any call like "esp32_wifi_get_xxx()"

For the above case, do I still need "WiFi NVS Flash" in the configuration?

I need to free up the NVS occupied by WiFi, which takes about 6K-9K. Am I missing anything that makes WiFi NVS Flash is a must?

Thanks.
