Hydraulic Disc Brake Dual Control Lever
The ST-R9170 Hydraulic Disc Brake levers have two e-Tube ports each and weigh about 160g per lever.
They do not feature the dedicated sprint shifter port, so using the SW-R610 sprint shifters is not possible.
If you really want sprint shifters then the SW-R9150 sprint shifter is the alternative. These shifters are a bit bulkier than the older sprint shifters, unfortunately.
Just like the ST-9070, ST-R8050, ST-R8070, ST-R9150 and GRX levers, these ST-R9170s have a hidden button on top of the hoods.
I wrote an article on setting up the Di2 shifter hood buttons, so have a look if you haven't set yours up yet.
