New Chateau 5G R17 ax

I'm looking for the new Chateau 5G R17 ax, product code S53UG+5HaxD2HaxD-TC&RG650E-EU

Does it have the modem soldered onto the board or does it have a regular modem with an M2 connector?

There is any pic of the inside ?

Not sure but I think LTE kit devices uses Mini PCIe modems, others have it on board.

The code Is
S53UG+5HaxD2HaxD-TC&RG650E-EU

The RG650E-EU Is the code of the modem, usually if It is a mini PCIe, It Is also for sale by itself.
Since It seems like It Is not, It Is likely that It Is integrated on the main board.
