RockPi4 SE with 4G Module

hi, i am currently using the Up4000 board with a riser card and 4g module for a large project, but, due to lead times, and cost, i am looking at alternatives. i have everything running great on the RockPi4 SE board, i have gone with this one as need 12v supply. but, one of the options i have is for a 4G module.

is it possible to do this with this board ? i have bought a riser from RS, but it is pretty clunky, and i still need a board to plug into that so the 4g module can be plugged in.

any advice would be greatly appreciated.
