Apparently, 2021.43.101.1 is the latest firmware, as of Jan 2022. I noticed the ANC missing, so I put in a service ticket to try and get them to push a more recent firmware but was told 1) that 2021.43.101.1 is the most recent available for the 2022 refreshed X's; 2) only Tesla engineering department schedules vehicles for firmware; 3) Tesla service can only re-push a firmware if the firmware has been pushed and downloaded by the vehicle; and 4) that my only recourse is to patiently await the newest firmware by connecting to really strong wi-fi. It's disheartening that they pre-load the newest vehicles with outdated firmware and there is no way for a user to self-retrieve/get the latest version without waiting and wondering. I also have to play their super-frustrating FSD beta qualifying 99+ safety score game again, despite having gained FSD beta access on my 2017 Model X.
I am in exactly same boat thanks for confirming we got the latest firmware.
