CHUWI HI12 - Android upgrade above 6.0 min


I own the CHUWI HI12 model number Q64G45170700…
It is currently using android version 5.1 .
Is there any way to upgrade the android version to newest version and at least version 6.0 ?
I don’t really use the dual booth option for the windows so i don’t really care about the windows .

Thx in advance
