Can I have two Stages of Electric Aux Heat with a 4th gen Nest?

I replaced my 5 wire thermostat cable with an 8 so that I could run two stages of aux heat with my First Co heat pump.

When I wired it up the Nest told me I can only have 1 stage of aux heat. What I thought I could do was have my heat pump run then to supplement my heat pump run heat pump + aux 1. If that still struggles run heat pump + aux 1 + aux 2 as the heat pump is capable. Is this not possible on a 4th Gen Nest?

I can't enter Pro setup without a Pro ID on the 4th Gen. My 3rd Gen I could just bypass it. If It's possible to run two stages of aux heat is someone able to help me get there?
