There are some protocols to access I2C devices, so the=20 implementation of the Firmware Management Protocol for an I2C device can use the I2C protocols to perform the I2C transactions to update the FW storage device on that I2C device. I am not aware of a standard for updating firmware devices on I2C busses, so a new UEFI Driver would be required. Please let me know if there is a public standard for=20 this operation that I am not aware of.
