How to apply bitbang on i2c lines to 11 bit shift register in code ?

I am using vcsel driver that i thought uses i2c but it uses two wire serial interface with 11 bit shift registor 3 for address less than the usual 7 bit address and I heard I could bitbang but I couldn't find it possible anywhere please look at datas...

I am doing i2c code with multiple slaves but one of slaves which is vcsel laser driver only contain 11 bit, 3 for address and eight memory I have no idea how to communicate and tell it to emit laser. I am trying to use memory address 001b.
