I want to buy a  laptop that has Maple Ridge NVM version 43.3 or newer.  

What is the Thunderbolt Controller NVM firmware version of the Razer Blade 17” (2022) | RZ09-0423 ?

The NVM firmware version can be displayed in Windows using the “About” option of the Thunderbolt Control Center app.  The “Thunderbolt generation” field should be “Thunderbolt 4 (1137).”
