nvram command failing on macOS Sequoia (M4 chips) but works on Ventura (M2) — C# tool

I'm developing a macOS tool (in C#) to read or modify NVRAM variables, specifically boot-args. My code runs perfectly on Apple Silicon M2 Macs with macOS Ventura, but consistently fails on M4 chips running macOS Sequoia. In C#, I execute: Executer.execute("nvram", "boot-args", null, true, false, true, true, out stdout, out stderr, out exitCode, out killed, 60); On Sequoia, exitCode is always non-zero, and the command can’t read or write NVRAM. Has anyone faced this issue on newer macOS/M4 hardware? Are there changes in Sequoia or restrictions I should be aware of? Any workarounds or solutions? Thanks!
