How to change RaspberryPi I2C speed in Simulink generated code?

when generating code from Simulink for RaspberryPi 3, the generated code always sets the I2c speed to 100 kHz. The generated code looks like this:
localDW->obj_gt.BusSpeed = 100000U;
i2cname = 1;
MW_I2C_SetBusSpeed(i2cname, localDW->obj_gt.BusSpeed);
Is there any way for Simulink to automatically generate I2C speed different from '100000U'?

Could you set it up from Hardware Implementation pane > Target Hardware Resources > SPI > SPI0 CE0 Bus Speed (kHz)?

Well, I assume that your suggestion is applicable to SPI, not I2C.
