M.2 E Key used for GPS and 4G /LTE

Hi,

I would like to ask if anyone has tested a 4G-GPS module with Rock 5B SBC. I am wondering if it could be connected to M.2 E Key port directly or through an adapter like this one:

I would need to use the rock 5B with 4G connectivity and with GPS also in the most compact form.

Thanks in advance for your answers.
