[D]How to deal with semantic segmentation datasets?

In segmentation there is usually a lack of datasets, so I want to use more than one. For example, let’s say I want to segment four classes, cars, buses, bikes, and background. background anything other than the vehicles.

I have three datasets, two of them have ground truths for cars, busses, and bikes but the last one doesn’t label the bikes and just ignore it. I want to use all datasets, is there a trick where I get away with this. I’m using softmax and use logic nor to get the background. It worked using only the first 2 datasets but I want to add the last dataset. I wrote this question and I didn’t get an answer in StackOverflow. Thank you
