How do I change the softi2c statement of micropython to i2c?
i2c = SoftI2C(scl=Pin(MPU6886_SCL), sda=Pin(MPU6886_SDA))
The uiflow I use does not have softi2c

This is a big problem. According to my superficial understanding, you are probably using a relatively old version of micropython firmware, and this SoftI2C is only supported by a relatively new version.

The UIFlow you mentioned refers to the WebIDE " UIFlow " developed by the M5 team , right? You can go and see if they have any new firmware for you to use.

Yes, my uiflow is already the latest version, but it still doesn't work. I tried another method.

In the earlier version, software I2C was defined by i2c = I2C(-1, scl=xxx, sda=xxx). In the new version, this method is cancelled and SoftI2C needs to be defined.
