In a word, yes, they are required for most cameras. I don't know much about your particular camera, but you probably have some form of cooling and temperature control. Whatever temperature you are shooting your light subs at should also be used to shoot bias and dark frames. I build a library of bias and dark frames for the typical narrowband and LRGB sub lengths that I shoot with my various scopes (and if you have gain/offset type controls on the camera you should shoot bias and darks using the same settings as the lights). Once you have built up a library of bias and darks you can build Master Bias and Darks using a stacker like DSS or other processing tools, this means you do not have to restack individual bias and dark frames all the time if your settings remain the same.
