Each of the fuel switches on the 787 is equipped with a locking mechanism that is supposed to prevent accidental movement, experts said. To turn the fuel supply on, the switch must be pulled outward and then moved to a “RUN” position, where it is released and settles back into a locked position. To turn the fuel supply off, the switch must be pulled outward again, moved to the “CUTOFF” position and then released again.

Or they could be inadvertently flipped if the "locking" version was not installed: (see the avherald link):

>>India's media report that the investigation is NOT focussing on a human action causing the fuel switches to appear in the CUTOFF position, but on a system failure. Service Bulletins by Boeing issued in year 2018 recommending to upgrade the fuel switches to locked versions to prevent inadvertent flip of the switches, as well as the FAA/GE issued Service Bulletin FAA-2021-0273-0013 Attachment 2 relating to loss of control issue (also see above) were NOT implemented by Air India.

I’m sorry to tell you this, but that appears to be an AI hallucination.

None of the attachments reference the fuel cutoff switches.

The peer comment to your own has a link to a real doc that supports the claim:
