Di2 riser handlebars or stem

[daddyo]

Looking for a Di2 riser handlebar and stem. My older Focus Jam2 with Shimano e8000 is still a great bike but I really need to raise the handlebars. My other ebike got a great upgrade the SQlab 30x 45mm riser handlebars a few months back and now when I ride the Focus I realized how much better it is to ride with a higher handlebar. So far I found nothing, either a stem or handlebars with the Di2 system. Any tips from anyone ? Thanks !
