I think it is theoretically possible. I looked up on the internet a device that has the same chipset (SD 662), Motorola G30 appeared to be one. It has 90Hz 720HD+ display.
It should be as just changing the display to a higher refresh rate compatible display that we want. Add some kernel options, drivers, and done. (Might not be simple, I don't know tho because I don't write kernel code, just speculating...)
EDIT: Here is Moto G30's specs: https://www.gsmarena.com/motorola_moto_g30-10724.php
