None.
I had a Razer laptop in the past when they were talking about being dev laptop forward & supporting Linux.
This never happened. Instead flashing Linux voids the warranty now, support drops you, & firmware upgrades only happen thru a green-accented genuine Microsoft Windows GUI installation (no *.bin flashing, no CLI FreeDOS support, no Windows PE).
To upgrade the UEFI or other hardware-level firmware you need a way to upgrade. Best OEMs use LFVS; good OEMs use have ISOs or bin files you can flash from UEFI; terrible OEMs lock that into a Windows-only executable.
In my case there was a fan & thermal update I was never able to get.
