Waveshare rp2040 display

feels like banging my head against a brick wall while downloading half the internet
default pins 4 and 5 have lcd display critical fault 3 as lora hardware connected to these pins- not obvious to me on

so I’ve tried other pairs of pins for sda and scl with it not found on auto screen.
spent hours fighting visualstudio code and platform.io complaining about depreciated issues
eventually after staying up all night to build uf2 file with pins 6 and 7 mapped serial 3 and no screen on auto.
I believe that the firmware isn’t searching pins 6 and 7 as I know the screen works and unsure which file to edit for screen
Pins_arduino.h
#define PIN_SERIAL3_TX (6ul)

#define PIN_SERIAL3_RX (7ul)

platfomio.ini
// default I2C pins:

// SDA = 6

// SCL = 7

I’m out of ideas

thanks
