Orifice, 1st Company

So I am assigned to install a condenser made by first company.
Was told to not use a TXV.. I pop open the installation manual and it says that the unit should be paired with an evap coil that’s fitted with a thermostatic expansion valve. As a result, subcooling is the process in which you charge the system.
Does this mean that it MUST be used with a TXV? Can an orifice be used?
first co’s tech support is closed for the weekend.
Attached is a photo of the install manual regarding charging
