[FR] Allow changing i2c source address for DDC Requests

[tinkererkzy]

I have a LG Monitor that allows input changing by writing values to DDC VCP Code F4 to i2c address 0x50

is there a way to allow TT to send some requests to this alternate address and others to the normal address to enable input switching on this monitor?

I may add support in my time too since i do have js knowlage

Actually this is a bigger change cause windows does not support sending to 0x50
So NVAPI or whatever thing that intel/amd support would be required

also more info on what i mean:
