Yes, it does. I've just checked and confirmed the presence of /usr/bin/lsblk on a Debian 12 liveUSB.

...

"Officials have begun following the new PC, laptop and server guidelines this year, after they were unveiled with little fanfare by the finance ministry and the Ministry of Industry and Information Technology (MIIT) on December 26. They order government agencies and party organs above the township level to include criteria requiring “safe and reliable” processors and operating systems when making purchases. "
