Luckily my cloned NVME came from another NVME configured for UEFI. So, some new computers don't support MBR.
The OP's Inspiron 5570 (2017) likely shipped in UEFI mode with Secure Boot and GPT. It should offer Legacy mode, which the Debian installer should detect and use MBR partitioning.
MBR works well with my imaging strategy because I only need to backup/ restore the first ~15 MB of each OS device. GPT would require me to also deal with the backup partition table, whose location can change if the source device and destination device are different sizes.
