Not exactly. But you can try clear nvram in some UEFI firmware interfaces. Otherwise, shutting down the PC, unplugging it, and removing the CMOS battery for a few minutes should reset it.
Got it. What about wmic memphysical get MaxCapacity—does that show NVRAM details?
No, that just shows your RAM capacity. If you want to check TPM NVRAM, you can use tpm.msc or PowerShell commands like Clear-Tpm.
That makes sense. So for actual NVRAM reset, I should check BIOS settings or remove the CMOS battery?

Yes that’s the best way.
