STM32F051K8, I2C pull-ups

hello

started STM32CubeMX and selected the stm32f051k..,

then added the  i2c peripheral and then selected the configuration->connectivity->i2c1 and finally gpio settings

noticed that the GPIO Pull-up/Pull-down drop down boxed could be selected for SDA and SCL

is this selection valid?

could the board pull-up resistors be eliminated?

checked the schematic of the stm32f0 discovery board (MB1034.pdf) did not notice any pull up on pins pb6, pb7 or pb10, pb 11

please let me know

regards

enzo
