@MLE_online In case it's of interest to anyone reading this: the datasheet indicates these can be locked down using eFuse bits that "can't be unset" (paraphrase) I would expect these to be set on an IoT device (tho' some of the products I've seen written about here… yeesh. so you never know)
I didn't find info for ESP32 about resetting these, but for AVR chips this has reportedly been possible, with some detail here: https://web.archive.org/web/20210506151334/https://sites.google.com/site/pbykec/projects/index/hvsp
hopefully it gives some helpful clues.
