No, but you can install a blue light filter program on your PC. Then it works not only for calibre but for all other programs as well.
I have one on my Ubuntu Laptop. But there are also for Windows, OS X and Android.
Or you just change the color settings in the reader and save it as a theme. And switch themes, with different color/temperature tints, whenever you feel like it.
