You are really bringing your own OS here. The nanopi can run mainline linux and u-boot[0]. If you suspect an Intel ME-style component with ring -3 access, it should show up in the initialization sequence - there are no blobs here. Features like these are not cheap to implement, especially when Chinese vendors are so keen on cutting costs. Essentially, this means that there is zero risk, unless you are a target, at which point any unintentional hardware bug caused by the aforementioned corner-cutting will become a concern.
