sudo apt install 'nvme-cli' -y && sync

sudo dnf install 'nvme-cli' -y && sync

sudo nvme format '/dev/nvme0' --reset --ses='1' --pil='0' --pi='0' --ms='0' && sync

• This works fine on a few Acer and Dell laptops, but could potentially cause a brick with bad platform implementations, use at own risk
• Safer way is to use efibootmgr to remove boot entries

sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v
