ODYSSEY-X86J4105 - I2C speed?

So the wiki says it is 1 Mbps. And can’t be changed. Is there any workaround for that? I need to talk from that SBC to the SMBus device that is basicaly I2C but limited to 100kHz. So I’m stuck? Any ideas?

Can Seeduino/Arduino talk over SMbus at 100kHz? and pass that info into the linux host system somehow?
