i2c on GPIO3 will affect the usage of the USB Serial/JTAG Controller?

I'm a beginner and I want to know if using sar_i2c_sda_1 and i2c on GPIO3 will affect the usage of the USB Serial/JTAG Controller?

According to the topic, when using the USB Serial/JTAG Controller for code uploading and serial output, will there be any impact if I only use the USB D- and D+ for operation? Will it affect the use of GPIO3 in I2C mode?

By default, all those eFuses are 0 so GPIO3 is ignored wrt configuring USB-serial-jtag, so you're free to use it for whatever.

Thank you very much. I have been wondering for days.
