Open gparted, create a single ext4 partition with unallocated space. This will be for lvm/luks. The filesystem does not matter, we simply need to create a partition here so that it's allocated a device node and shows in /dev). Create LUKS container on this partition (assuming the partition device is /dev/nvme0n1p5): a.1 large partition that will be encrypted (by LUKS) and managed (by LVM2) to consume the rest of the drive space. Given those assumptions, you must. create a 500 MB boot partition in /dev/sda1; give all remaining space to a single partition== /dev/sda2; unless you have done that already.
