you would probably need to find out what is the lcd controller for the lcd and the pinouts for those pins
it looks somewhat like a 8 bit or 16 bit parallel interface to me

Yes, the 5 resistor packs imply a 16-bit parallel interface.
The microSD does not use a resistor pack for level shifting.

It is a mystery why anyone would buy a Shield that is designed for a 5V Mega2560 and then want to connect to a 3.3V BluePill.

I suggest that you plug it into a Mega or Due. Identify the controller and geometry by guesswork.
And having narrowed it down, do a few diagnostic tests to distinguish between Makers.

MCUFRIEND_kbv supports many 240x320 controllers. It does not currently support any 128x160 or 176x220 controllers.
It does support Mega2560 shields in both 8-bit and 16-bit as SPECIALs.
