Dual gps configuration on Emlid Reach M2 with CUAV X7

I’m planning to running dual gps as blend mode in AC 4.0.4 as GPS type 1 is CUAV V2pro GNSS connected via CAN1 on the CUAV X7 .

Now I want to connect emlid reach M2 GNSS with RTK enabled .now my question is whether I want to run the emlid gps as GPS type 1 or CUAV v2 pro GNSS as GPS type 1.

If emlid is gps type 2 will this perform RTK mode in flying and use emlid gps for RTK navigation ?.

As @Randy Mackey suggest that use both GPS as same manufacturers but here I want to perform RTK mode .will this my set-up work or modify some parameter?
