Can we disable Flash erase function?

[Dakshk]

Hello,
I am working on ESP32c3 dev kit and wondering that if flash erase can be disabled or not. I found sources and according to them we can disable flash erase by disabling UART download mode, but if I do not want to disable this feature can I explicitly disable only the erase functionality?

Thank You

Flash memory must be erased before new data can be written to it, so ...

Why specifically would you want to disable such a specific function?

I want to use UART for other communication purposes and along with it not allow anyone to erase it through UART using commands, so I was wondering if I can disable that particular command.

Why not use different pins to connect your peripheral to? On bootup, you can have the settings as-is, maybe with txd and rxd connected to a debug header inside the device or something. When your app starts up, it re-initializes the UART but connects it to pins where your actual peripheral lives.
