Really? That's terrible. I often update UEFI settings.
Do you have a source for this?
I can't find any. There was a bug that made NVRAM read only on some
systems in 2017 (that was in ubuntu 17.10), but nothing else I can find.
I can find some comments about trying to reduce the writes to NVRAM to
avoid wear, but nothing specific I can find that actually says people
have had NVRAM actually wear out. It would have been some years ago.
Years ago I worked on an avionics project where we were storing data in
an NVRAM.
We had to write code to manage the wear-out in the cells and if I
remember correctly the wear-out was in the hundreds of thousands to
millions of writes before problems would occur.
I could not see normal usage causing wear-out unless someone were to
have some kind of bug causing a high write rate.
