Expand range on xt FC-M5100-2 cranks

I am wanting to convert Giant toughroad SLR from 2×10 to Di2 2×11.
It has a QR 135MM rear axle and am told it should accept a shimano 11sp cluster, say the CS-M8000 11 46t

The xt cranks are 26 36 which does not have big enough range. My current cranks are FSA v drive 32/44. And this is the preferred range. Can I get alternative chain rings of the 32/44 size or is there a better way to do this.

Thanks for any help.
