I2C-1 standard pins: PB7(sda) PB6(scl)
Use it by "Wire" without pin declaration
Wire.begin();

I2C-1 alternative pins: PB9(sda) PB8(scl)
Remap the first I2C before call begin()
Wire.setSDA(PB9);
Wire.setSCL(PB8);
Wire.begin();

I2C-2: PB11(sda) PB10(scl)
Remap the second I2C before call begin()
Wire.setSDA(PB11);
Wire.setSCL(PB10);
Wire.begin();

If you want to use the two I2Cs simultaneously, create a new instance for the second I2C
TwoWire Wire2(PB11,PB10);
Wire2.begin();
