Size and speed issues aside, this probably won’t work at all. My understanding is that many m.2 slots are multi-purpose, with nvme, data, and USB data pathways. Most adapters like this just connect the micro SD to the USB pathways in the m.2 slot.

As far as I know, the deck has a NVNE only slot, so something like this that requires the USB part of the m.2 slot won’t work.
