MAX HD4 use 1 SIM admin and 1 Sim Crew in same interface

I’ve got a customer that have MAX HD 4 LTE and wants to divide the traffic over interface 1 between a dedicated SIM for Admin in slot A and a dedicated SIM for Crew in slot B on the same interface / carrier.

The traffic can be distributed on separate vlan to Admin and Crew. They want a solution where you run static IP on Admin and DHCP on Crew, does anyone have a suggestion on how to configure such a solution?
