what makes u think it's not "supported"?
usual chips, TFT ILI9341 + XPT2046 touch.

I think the board has another screen that needs a variation of ILI9341 driver. Using TFT_eSPI library I need to take ILI9341_2 driver.

[lsdlsd88]

try this alternative panel file. u can replace into yours just for testing

After completing lines 79 and 80 with commas the driver works.
I'd set the Gamma in lines 50 and 51 to 0 to get better colours:
static constexpr uint8_t CMD_GMCTRP1 = 0; // Positive Gamma Correction (E0h)
static constexpr uint8_t CMD_GMCTRN1 = 0; // Negative Gamma Correction (E1h)
Please see discussion at Bodmer/TFT_eSPI#2985

Strange on my side this one is working (Need to use ILI9341_2 too on TFT_eSPI lib, USB type C model).
But it works fine with LovyanGFX with
