Preventing further writes to the fuse bits

[vinodstanur]

Hi,

I want to prevent further writes to fuse bits to prevent any future accidental writes.
For example, I am using flash encryption but not secure boot. So in future if my program can write to the fuse bits by mistake, I don't to take a chance. So is there any way to freeze the current fuse bits to prevent any further writes to it ?

I am using espefuse.py command directly and I am not familiar with the idf.py script. I am using 3.3 stable esp-idf in linux.
