here is link to the latest release Release v0.4.2 · FrameworkComputer/framework-system · GitHub
please keep in mind that it requires crosEC driver Release CrosEC v0.0.2 · DHowett/FrameworkWindowsUtils · GitHub which requires disabling secure boot and enabling test signing. as an alternative you can use ectool. I forked GitHub - DHowett/ectool: ectool, isolated from the ChromeOS code, and with some Framework-specific support repo and merged PR which uses winring0. it works with secure boot enabled. here is link Release Release aa-a00923cf-bb · wmigas/ectool · GitHub and please keep in mind, that you need other application to load winring0. it can be open ahrdware monitor or universal x86 tuning utility. see PR for more details.
