Hi @Shealtiel ,
Which mode you want to use? if you are used the unsigned mode, it won't burn the fuse, but, if you choose the BEE, HAB related operation, it will burn the fuse.
To the secured program, it will help you to burn the related fuse, to the second secure program, it won't burn the fuse anymore, just download the app.
So, it is totally determined by your usage.
Wish it helps you!
If you still have question about it, please kindly let me know.
If your question is solved, please help to mark the correct answer, just to close this case, thanks.
Any new issues, welcome to create the new case.
Best Regards,
Kerry
