Coral Edge TPU M.2 (B + M key) in "M2X extension board"

Hello.
Is it possible to connect to the “M2X extension board” in the “M.2 slot (B-Key)” not an LTE module, but other boards?
For example Coral Edge TPU - M.2 Accelerator B+M key | Coral
Connector: M.2 (B + M key)
Dimensions: 22 mm x 80 mm (M.2-2280-B-M-S3)

@Ruvejahu It’s not available now. We are already cooperating with upstream to deal with this driving problem.

Thanks.
Software incompatible? Or hardware?
