There are some older models that can only boot from the DOM, however most newer ones (especially the AMD Ryzen ones, which i personally would highly recommend) have no issue. The early TS-X77 models do not boot from NVME, but that can be overcome with some creativity :)
Wait which model line? I never knew one could run their own OS on QNAP

Hmm, how do I know which models can only boot from the DOM? AFAIK Terramaster NASes don’t have such restrictions.
