[BBAI] disable Driver for STMPE811 on I2C1

I have written an I2C driver for PRU on the Beaglebone AI and I want to make some I2C transactions between i2c1 and the STMPE811. However, there are some Kernel driver already using it. I have tried to unload the kernel module “stmpe-adc” (with rmmod at run time) but this does not free the resource and the result of i2cdetect on the I2C bus 1 still give UU for the address of the STMPE811 (the resource is still busy). I would like to know how can I free this resource to be able to use it with the PRUs?
