You have an ILI9481 with 8080-8 interface.
Install MCUFRIEND_kbv library with the Library Manager.
Plug the Shield into Uno, Mega, Zero, Due, ...
It should work 100%.
Note that this particular Shield is prone to overheat.
If you want to know how to do "low-level" driving, study how to set a bit in C with |= and to clear it with &=~
Then ask as many questions as you like.
The 0x10 command is the same for any MIPI compliant TFT controller e.g. ILI9341 or ILI9481.
