Considering how little documentation there is for the i10 I wouldn’t recommend completely removing either OS but I found most guides for the Chuwi Vi10 and the Teclast X98 apply to this tablet as well, though not 100% so be careful.
If your SD does not appear in Windows 10 then it is not supported by the card reader or is not formatted correctly. Most cards over 32GB don’t work at all anyway.
So what I did to increase size in Android was take a bit from Windows 10. I increased Android to 5GB. Here is how you do that:

You’ll need:
A USB Keyboard to access the BIOS
A compatible USB flash drive
An ISO of gparted
LinuxLive USB Creator
A couple notes:
When you’re using AOMEI Partition Assistant if your disc doesn’t appear go to System > Reload Disk in the program.
Before booting gparted from USB go to the BIOS by hitting ESC on the keyboard when the tablet immediately turns on and changing ACPI from 5.0 to 3.0 or else it’ll either hang when scanning for partitions or take a LONG time. Like hours potentially.
