lacking GPIO pins

Hey, I'm working on a project and I need to integrate a Lux sensor module using 2 wire I2C but I happen to find myself to have only one pin available and thats 28 (GPIO 1). I can't interfere with other pins. If you ever experienced or know how to solve it please help me. Thank you.

All of the not used pins are ground or power only 28 isn't. Also i'm using raspberry 4

tbh the only proper solution i can think of is somehow making more pins available

I2C is assigned to some GPIO pins and if they aren't available then you only option is a USB adapter.
