Dark libraries are a common tool imagers use, just as long as you have sets that match sub exposure duration and temperature setting. Bias is the same. Some cameras can actually get away without Darks, like the ASI1600MM-C, IF you are shooting subs of short duration (say 30 secs, up to 60 sec) where there is no detectable AMP glow, just use Bias in that case. It is up to you, look at the Bias and Dark histograms and see what you think.
Of course the ASI294 is a different sensor, and has different needs, and issues. From my research it seems to require Flats as well, given the uneven sensor cooling producing gradients (a product of the back lit architecture not allowing a full sized TEC).
