How to set up "Standard ESP-NOW" mode

I try to test the range and throughput of ESP-Now standard mode like your video on Youtube

But i don't know how to set up ESP-NOW in standard mode
I try to delete the code :
#if CONFIG_ESPNOW_ENABLE_LONG_RANGE
ESP_ERROR_CHECK(esp_wifi_set_protocol(ESP_IF_WIFI_STA, WIFI_PROTOCOL_LR));
#endif
But I still get the same result before I delete it
What should i do to set up ESP32 to "Standard ESP-NOW" mode.
Thank you very much

No repository file or test is named. Start by tracing the ESP-NOW and Wi-Fi protocol configuration around CONFIG_ESPNOW_ENABLE_LONG_RANGE and esp_wifi_set_protocol, then compare the resulting behavior with the reported range test. Done means documenting the steps for selecting standard ESP-NOW mode and explaining why removing the shown block did not change the result.
