You won't. That is part of the fun dealing with Shimanos crankset hese days; they are unique, FOr instance, the FC--M985 only comes in matched sizes of 28/40t or 30/42t chainring configurations. Also, if I am correct, this XTR 2x10 Crankset uses an 88mm Bolt Circle Diameter (BCD) that is unlike anything else on the market.

If you want to be able to chaining gearing easily, then you should "downgrade" to a square taper compact (110 BCD) crenkset. Otherwise, learn to live with what the manufactures tell you is the "best gearing" (until they change it next year).
